    Thank you! You seem like you have found the exam easy, what grade are you aiming for??
    I didn't find it necessarily easy, but it wasn't extremely difficult. I think for this paper I probs lost like 8-9 marks, so overall I'm just aiming for an A. Hopefully if the grade boundaries are low I'll get an A* though. Fingers crossed! XD

    You got it right

    I did a stupid in the exam and wrote food can for painting >< I crossed it out but then I forgot to write car body asdfhjlkasdf.
    Do you think I got all of it right? OMG I hate that when you cross something right at the last minute and change it to a wrong answer.

    Does it need to be washed with distilled water?

    I wrote first you mix the components, stir them, filter the excess ammonia, heat some of the water and leave some of the water to evaporate under the sun.

    Nope that's only for preparation of insoluble salts, ammonium hydrogenphosphate (or whatever :P) is soluble.
    Anyways, I found it quite easy apart from the electrolysis diagram and the final question. Did you guys remember to write the volumes correct to the nearest 0.05 cm^3 ?
    The question about mistakes in the steps and the one about the calculated volume were the hardest in my opinion.

    The mistakes
    Step 1: use volumetric flask (?) instead of beaker
    Step2: MgSO4
    Step3: remove some water only 😂 so strange

    Wrong. You have to boil off some water and cool down the solution to get crystals. The crystals should be filtered and dried in an oven.

    You might lose a mark for this. If you wash it with distilled water, it will dissolve again. So you basically go into a loop.

    If you are going to wash, use small amount of cold water
