    do you have any revision sheets based on paper 3 which will focus on mainly practical, it would be very helpful if you could post a document like that which contains all of the practicals we need to know in a single document

  2. S.A.H

    hi, you said you have separated the AS and A2 topics so does this mean if i am giving A2 i do not need to study from any of the AS notes. Im sorry about such a silly question but the new specs are confusing.

  3. Samuel Ida

    It seems that you’ve made a mistake on polymers guide on the second last page. It says that polyamides form hydrogen bonds between C=O and N-H which cannot happen as hydrogen bonds only happen between molecules with an electronegative atom DIRECTLY attached to hydrogen. It will still display hydrogen bonding between N-H bonds though.

    For your ‘kinetics’ revision guide, there’s a small inconsistency I think.
    Some of your Maxwell-Boltzmann curves have the y-axis as ‘fraction of particles’ whereas others have it as ‘number of particles’. Usually this would make no difference but if you’re talking about the height of the curve, it’s an important distinction to make. Could you please clarify which is the correct term?
    Thanks, your notes have been really useful.

    1. chemrevise Post author

      Both are correct terms and are used interchangeably but if you wanted to show effect of concentration it makes more sense to use number of particles

    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?

  6. Mia

    are the revision sheets that haven’t been updated still relevant to the new spec or should I wait for you to update them before I use them

  7. thanushan

    how comes on the metal aqua ions revision sheet, there’s nothing about the ligand substitution of hexa-aqua ions with chloride ions. Do we not need to know that for our spec?

  8. Zachary Howdle

    I think this is a brilliant resource and thank-you so much for taking the time to create it. I was wondering if there are similar compact revision notes for Physics or Biology?
    Thanks again!

  9. thanushan

    is it possible for you to make a separate document with all the mechanisms and routes we need to know for our final exams, please it would be very helpful.

  10. Aysha


    I’m resitting a level chemistry with the old syllabus. When I was in year 12 I remember you used to have a summary of all the mechanisms under chem2 as a separately document but it’s not there anymore. I was wondering if you could upload it again?

    Hi, thanks for your notes, they’re very helpful 🙂 I noticed a mistake in the AS atom revision guide. The mass of 59Ni+ should be 9.797*10^-23g not 9.979*10^-23g

    Hi, I’m wondering if there is any website, or anything you might advise me to use, has exam questions with answers per topic for aqa chemistry.

  15. Emma

    For deducing rate equations, what do you do when there is an acid catalyst so H+. Do you include that in the rate equation?

  16. student101


    Firstly I would like to thank you for your contributions they have helped countless students. I am currently in a bit of tricky situation and would like your input and advise. I have sat the whole A-Level chemistry for the old specification but if I need to get the grade I want I will need to practically sit all the exams again. I am considering sitting the new specification AQA again as content is very similar I am just unsure about the 12 practicals. Could I do this while self-studying?

    1. chemrevise Post author

      The 12 practicals are pretty standard and should have been covered on the old syllabus. If you are doing it privately you could not the get the practical competency award but this is independent of the main grade

  17. Emma Holden

    There are some guides which don’t say ‘updated August 2016’ is that because you haven’t gotten around to doing it or is the syllabus simply the same as previous years for them particular sections?
    By the way- These are great

  18. Sharon Jacob

    Please can you post the amino acids section for the A2 New Spec AQA soon as my summer homework is about it?

  19. River

    Hi there,
    Can I just ask, are the New specification revision notes for AS and A2 or just AS? If they are for both years, how can I distinguish between the notes because I am starting year 12 in September and want to get a head start in the summer? Thanks in advance.

    when is a platinium electrode used? and for cell represnetations which of the molecules should you include?

  21. selma

    in unit 5 redox equilibria, for Fe2+ (aq) -> Fe3+ (aq) + e- , this is oxidation so why is the cell representation | | Fe3+ (aq), Fe2+ (aq) |Pt, with the half cell on the right
    and not Pt| Fe2+, Fe3+|| with the half cell on the left , as the oxidised and more negative E half cell goes on the left

  22. Prospective medic

    Thank you for the fantastic notes Mr Goalby! Have you had the opportunity to look at the 2016 chem4 paper yet? Do you have an opinion on it if so?

    1. chemrevise Post author

      It had some tricky questions and some quite straightforward questions that were made to look tricky by unfamiliar compounds or contexts. I can understand why many students would not have liked it.

  23. lebzz

    i was wondering when are you gonna do notes on the new aqa second year of A level just finished AS level i want to start revising for second year of A levels over the summer holidays. i would really appreciate it if it was released as soon as possible.

  24. Mo

    Can I just say that these notes are absolutely awesome. They’ve been of huge help. A quick question. In the section of organic analysis on new spec-3.6(page 3) in the table of functional group tests, for the test of primary, secondary and aldehydes, it says that the reagent is sodium dichromate. Should it read potassium dichromate? Thanks

  25. Jean

    Hiya, in the transition metals booklet, the last page with the summary of chromium reactions, you put [Cr(H2O)2]+3 as a green solution but I think it should be blue.

  26. David

    Hello chemrevise!
    I would just like to thank you for your awesome notes first, it’s really amazing.
    The only question I have is that when you add excess OH- to Al(H20)3(OH)3, the notes says its Al(OH)4. But in the aqa mark scheme it’s Al(OH)6. So could you just clarify on this please? (Chem5 Jan 11 6b) thx!

  27. Nina

    Hi, firstly I wanted to say thank you so much for these notes!

    I was just wondering if this was a mistake on the 1.1 AQA revision guide

    The 160 peak has double the abundance of the other two peaks because there is double the probability of 160 Br79-Cl81 + as can be Br79-Br81 and Br81-79

    Shouldn’t it be 160 Br-79-81 and Br-81-79 only, why is it Br79-Cl81?

    Thank you! 🙂

  28. Mehwish

    Hi. Would I need to revise for the ‘experiments’ section in the calculations revision guide included in module one for the unit 1 exam or is that information only for practical exams? Is there a chance that it may come up for the chem1 exam?
    Thanks 🙂

    Quick question regarding hydrolysis of polyamides.
    In your notes it says that HCl and a polyamide will be hydrolysed and split up into the original carboxylic acid and diamine salt. It also says it’s split up into the same thing with NaOH. Is this correct? I’m just a bit confused as to why this occurs with both HCl and NaOH with a polyamide but not with a polyester?

  30. Alan Smith

    Is there a mistake on page 12 of transition metals (module 5 of the old specification) in the EDTA titrations? In the question, it talks about titrating EDTA4- against [Cu(H2O)6]2+ but the first step in the solution is to work out the number of moles of KMnO4. I believe that this is a typo and should be to work out the number of moles of EDTA4-. Please could you confirm this?

  31. Junaid

    Not sure if its a mistake, I may be mistaken, however in old aqa spec, A2, Transition metals you state on page 4 the general equation is M(H20)6 to M(OH)4 when making it alkaline, Shouldn’t it be M(OH)6 ?

    Please could you upload the notes you have so far for 3.15 NMR and chromatography. Getting tested on it next Monday. Thanks

    Hi in your atom revision guide 1.1 you said for electrospray ionisation:
    “•The particles lose an electron ( or more)”

    This is what I thought, it is also in the textbook I use, but on the mark scheme of the specimen paper 1 for the new AS course it says ‘M gains a proton forming MH+’ for electrospray ionisation???

    1. chemrevise Post author

      Aqa appear to have updated the science on this over the year and have changed the mark scheme to this question. It does now agree with some supplementary notes they have issued on the mass spectrometer. I will update my notes soon. When the officially endorsed textbook says the old idea they can hardly penalise it though so I wouldn’t worry which version you learn.
