18 was A, I think.

There's a few others I got different in there, too...

I'm pretty sure it's all right except..
12 - D (decreasing order)
13 - C (solid doesn't affect equilibrium)
15 - C

Im feeling pretty confident about them, some were tricky, i think i got the bromine water one wrong, out of panick. And i didnt get to check my calculations due to time but my answers seemed not too bad. 15 i think was quite tricky. But im happy with the conclusion i came to :) hopefully 17-18

Yupp, because theyre both monoprotoc, the degree of ionisation woll affect the end point, not the volume needed. Eg citric acid requires alot of strong base to neutralise despite the fact it is relatively weak.

Question 15 depends if you assume that the weak acid fully ionises or partially ionises. From the 2010 paper, there was a multiple choice question that assumed full ionisation of weak acids. Therefore, I assumed that the hsc expects you to say that weak acids fully ionises. Therefore, answer for 15 is A (I hope).

It ionises fully because of the fact that its a weak acid. Consider the equilibrium reaction in which the hydrogen ipns are produced. As the hydrogen ions are removed due to the hydroxide of the base. More of the acid ionises, hence it has to do with the amount of protons not degree of ionisation.

No...Citric acid requires lots because it's triprotic. An acid sample that is weak will not ionise fully.
