thank you for these notes,they have been very helpful to me and they are still helping me thank u so much

Josh September 14, 2019 at 5:18 pm

Hi, thank you for these notes! They are amazing! I would just like to raise your attention to the Halogens Revision Guide – For the reactions within this section, shouldn't the acid always be (aq) and not (s); and the same for NaHSO4? My Chemistry teacher also has seen this and agrees with me.

1. chemrevise Post author December 1, 2019 at 10:51 am

   It's a good question. It does look a little odd- I have sulfuric acid as an (l). I have checked with some academic sources and the l and s are correct. Concentrated sulfuric acid is a liquid rather than an aqueous solution. The NaHSO4 is therefore produced as a solid. I can't say I have seen a mark scheme where this has been tested but will keep my eyes open. It would be fine to write them both as (aq) though.

   these are the best notes i have ever seen in my life!!!!!!!!!!!!! soooooooooooooo helpful :)))

mosesdavis June 18, 2019 at 12:05 pm

Mr Neil, you have helped me with chemistry an extraordinary amount. The provision of FREE resources which would have taken you hours to complete in admirable, to say the least. The exam board specific, succinct notes have helped me beyond imagination. You, Sir Goalby are an angelic creature.

1. Mo H Davis December 20, 2019 at 11:04 pm

   I went from a D in the mock, 2 months prior to the exam, to an A in the final exam – all thanks to this resource. Especially the visual aid of the mechanisms; if you can learn that image off by heart you can do any mechanism question.

Hi, thank you so much for these notes they're life savers. I was just wondering where you have notes on the Arrhenius equation because they weren't in the rate equations section and I wasn't sure where else they'd be. They're especially important for me because my copy of the textbook (like quite a few others) is missing the pages on the Arrhenius equation. Thank you!

1. emmacampbell2000 April 3, 2019 at 1:31 pm

   Oops sorry, just found it! It just wasn't as obvious as I thought it would be.

Kermit September 4, 2018 at 1:56 pm

Hi, I'm retaking aqa chemistry a-level due to missing my grade for uni and was wondering how to go about my revision?

OH99 August 30, 2018 at 1:36 pm

Mr Goalby I would like to thank you so much for taking the time to write these guides. They, along with past papers and practice questions, were literally the only resources I used over the two years of my A-level. I'm delighted to say that I got my results two weeks ago and got an A*

So once again, thank you so much for these guides

How do you maximise the yield of aldehyde produced from the partial oxidation of primary alcohols?

1. Asks8aam June 12, 2018 at 11:44 pm

   Lol this came up in paper 2
   But I think you can collect it in a cooled beaker which has been placed in an ice bath as that minimises loss due to evaporation
   Also you have to ensure the temperature on the thermometer is at the boiling point of the aldehyde or just below it.

2. 111 January 2, 2021 at 12:50 pm

   you must keep distilling the aldehyde out of the reaction environment, most of the time with chemical reactions maximum yield is not reached because products are not being constantly removed at the correct time, if this is done the reaction proceeds faster hence yield increases(also if this is not done then the aldehyde will soon form a carboxylic acid by further oxidation, so it is imperative to be removed)

Hi Sir,
on the 3.6 analysis guide it says about m+4 for chlorine that the molecular mass is 102 but with 35 isotope and 37 isotope i think t sums to 100 instead. Am i mistaken?

Many thanks

Akash Digumber June 3, 2018 at 1:53 pm

Hi, are notes about Nitrogen and Sulfur are missing i think. Realized that after working out a past paper

1. chemrevise Post author June 3, 2018 at 4:32 pm

   Aqa does not have a topic on sulfur and nitrogen. Any questions that appear on them are from topics like group 7 , redox or equilibria. The only syllabus that has a specific topic on these is CIE international A-level

Mark June 1, 2018 at 3:05 pm

Hi,

On the right hand side of page 2 of '2.4 Periodicity of Period 3' it states that 'MgO is better than using NaOH to treat acid in rivers and the stomach as it is only sparing soluble and weakly alkaline..', should it be 'Mg(OH)2' instead of 'MgO'?

Thanks

1. chemrevise Post author June 3, 2018 at 9:05 am

   Same thing applies to both

barbosaboy7 May 22, 2018 at 4:22 pm

Hi, I took most of your notes down in December time last year in preparation for my exams this June and I have since noticed that some of the pages have been updated and I was just wondering if I will have missed out on any of this years spec if I don't go back through it all again?
Thanks

1. chemrevise Post author May 23, 2018 at 8:38 am

   The syllabus has not changed but I have made some improvements to the notes this year.

   1. ssj20 May 30, 2018 at 6:54 pm

      Great Notes
      Thank you

Demirci May 20, 2018 at 12:43 pm

sir, i do not like taking notes and the only thing i do is read.

Do you think these notes contain everything i need to get an A*.

1. chemrevise Post author May 21, 2018 at 10:44 am

   In terms of factual content yes it is all here. Just reading these notes won't get you an A* though. You need to do lots of questions and push your understanding

David Lesmana May 20, 2018 at 4:44 am

Is there note about solubility and solubility product constant (Ksp) ?
Thank you.

1. chemrevise Post author May 21, 2018 at 10:42 am

   The only place I have Ksp notes is in 7-cie-equilibria in CIE international A-level or text book 4-35-acid-base-equilibria chapter.

Jake May 15, 2018 at 9:20 pm

Hi Sir,
Thanks a lot for all these notes, they are fantastic, especially when dealing with some of the tougher questions which are appearing on this new specification. I wondered if you had anything that would help with questions like in AQA Paper 2 2017 (10.6), when drawing cyclic compounds from straight chain compounds. It is possible i have missed something already in your notes, however i did not come across it.

1. chemrevise Post author May 16, 2018 at 11:03 am

   I put some explanation of this in the chapter on condensation polymers.

Sir thank you so much for these amazing notes specially the summary for mechanisms

I will be grateful if you could do summary for test and colour with equations for year2 aqa inorganic please (transition metals and their reactions in aqueous solutions). I'm privet candidate, 100% relying on your notes. But I completely lost with year2 inorganic and transition metals, specially the new spec, I don't even know the compounds that I need to know about? Please Sir I really hope you will read my comment and do the summary before May.

Kas April 16, 2018 at 9:50 am

Hi, I really appreciate the time and effort that must've been put into making these revision guides. It would be really helpful if you could possibly list what is not required to be learnt for the new spec or something as I'm a private candidate and finding it quite tricky, thanks 🙂

1. chemrevise Post author April 16, 2018 at 4:40 pm

   If you want an A* then I think you should know everything on the guides. I would suggest going through the guides with a copy of the syllabus to hand so you can be sure why you the things are there.

2. Mary April 25, 2018 at 2:48 pm

   Hi, I would like to know what are the practicals we need to know for the AS exams? I know there is a practicals revision guide but I'm assuming some of the practicals are just for the year 13 A- LEVEL exam?

   1. chemrevise Post author May 5, 2018 at 8:19 am

      The first six practicals are AS

jesus the 2nd April 10, 2018 at 10:05 pm

perfect notes I hope it helps others

hafsa April 10, 2018 at 12:20 am

hey do we have to know about chromium for aqueous ions because it comes up in past papers but its not on your notes. thanks

1. chemrevise Post author April 10, 2018 at 5:54 pm

   No the syllabus changed

chemrevise Post author March 25, 2018 at 6:48 pm

There are test summaries in the practical guide

Joseph March 23, 2018 at 3:01 pm

Hello you have made a mistake on example 5 of the energetics questions on the aqa as level document you have talked about enthalpy change of formation when the question is about enthalpy change of combustion

1. chemrevise Post author March 25, 2018 at 6:47 pm

   It is not a mistake. They often combine heats of combustion and formation in the same question to confuse people and see if they really understand what they are doing. I suggest you look again and try to undo your confusion.

Kermit March 5, 2018 at 11:34 pm

I think you made a mistake in the transition metals guide in the first point where you wrote there are transition metal characteristics between scandium to copper. Isn't scandium not considered as a transition metal? Thanks….

1. chemrevise Post author March 10, 2018 at 1:40 pm

   The AQA definition for transition metals which is IUPAC as far as I interpret it does include Sc as in its atom form it does have a 3d electron. Definitions for other exam boards are slightly different and definitely exclude Scandium.

chemrevise Post author February 17, 2018 at 4:09 pm

yes

      It is unlikely there will be any changes now until end of year

Prakhar Gupta December 26, 2017 at 10:37 pm

Hi Mr Goalby, for your revision guide on the specification 1.1 (atoms), you talk about fragmentation in regards to T.O.F mass spectrometer. This isn't in the syllabus nor is it in the textbook, and I'm struggling to understand it. Do i even need to know it?
Thank you for everything!

1. chemrevise Post author February 17, 2018 at 4:11 pm

   fragmentation is not on AQA but is on OCR and Edexcel

Qaim December 6, 2017 at 4:53 pm

Hi,

I'm a bit confused on the question on page 5 of the equilibria pack. I was able to follow untill you wrote 0.458. I've no clue how you got it since it should just be a simple rearrangement?
Your packs are really useful and are what I'm using to revise for my Oxford interview next week,

Thanks

Hi, I wanted to ask on the equilibria section in physical chemistry, when calculating the moles at equilibrium mixture using algebra (page 5), how come on the numerator it is 2x? is this because there are 2 moles of HBr formed? ' (2x/V)2 (0.2-x)/V . (0.2-x)/V ' So if in another question, only 1 mole of product was formed, would it just be x?

1. chemrevise Post author April 21, 2017 at 1:53 pm

   It is because in the balanced equation 1 mole of H2 produces 2 mole of HCl
