    Ah ****, yeah. I see now.

    I thought it meant getting an acid from the salt.

    Completely disregarded the alcohol >.>
    I said heat under reflux so I'm in no position to judge!

    When I did the molecular formula question, I divided the 1.5...whatever it was by 2 and then divided all the numbers by that number to get the ratio for the molecular formula rather than obtaining the empirical formula and multiplying by 2. Full marks or would I end up losing a mark for this?

    The petition has made me feel much better but my chemistry grade is in serious jeopardy. I'm so worried i don't even think lowering thr grade boundaries will help me much. I'm scared I will get a U & it's even more frustrating because I panicked so much & ran out of time for questions which I would've otherwise been able to do

    I don't see why not!



    Adding HCl would turn the salt into a carboxylic acid and NaCl - it would then still be mixed with the alcohol.
    Did nobody else say fractional distillation? The alcohol has a different boiling point to the other compounds so it should be legit right?

    For the reaction with NaOH, could you use an acid catalyst as the conditions?

    Tbh, if they made a new paper in the old style with actual questions from the spec, I would be more than willing to do it!

    There's a petition to lower the grade boundaries on the AQA Chemistry 4 paper on "ipetitions". It's aiming to gather 15,000 signatures and can be found by either googling "lower grade boundaries for CHEMISTRY UNIT 4 2016" or going to the Facebook page "aqa chem4 complaints". It's at 4000+ currently and by getting friends and family to sign hopefully aqa will have to review.

    Yep same here, I'm resitting this exam so I was aiming to get a low A at best but now I'm most likely going to end up with a D again for CHEM4 and not get into uni - Thanks AQA

    Even if they do lower grade boundaries I still don't think I would've managed anything higher than a C, that exam was awful and my mind went totally blank and messed up on loads of questions, especially the synthesis questions, the 9 marker and the pH ones

    I didn't for both first and second. They'll allow either way, as the question referred to a reaction between but it was technically reversible (as is every chemical reaction depending on the conditions).

    Hey does anyone have a full list of colour changes that we need to know?

    Even tho aqa will probably ask us why surgical stitches are blue and not green 🙄

    That's exactly right
