It was a little difficult, but hopefully they'll adjust the marking scheme for that reason.

3 p.p.m. for Q1 d) iv) my friend got the same answer @Marzipan5 so I presume that's it?
Marzipan15
i got 3 p.p.m. as well!!! (3.125ppm) but rounded off it's 3ppm. I found that question really hard. hopefully we're right!! @PCasey00

Even Q 4 which is usually nice was awkward this year :( , I thought the weird questions about atomic orbit and orbital and the p diagrams were tricky too

can someone send in a picture of how to do Q1 d) part iv)?

@jessicao12 Yeah it was a hard question I got 40 degrees celcius. The hard part was realizing that the H+ ion concentration was equal to OH- concetration. You used pH formula ph=-log10(H+) Then say kw=(H+)^2 and find Kw value. Then use Kw to find temperature.

Thought it was a nice exam apart from the weird rates of reaction question. Happy out!

I usually have enough time to do 10 questions but I just got enough time to do 8... tough questions in there, much harder than the mocks.
