If you mean the x y and z you was meant to write two and I totally misread that so wrote 1. I am beyond annoyed because I memoried all the test for ions so they were easy marks:'(

What where the ions for the 3 compounds?

Me too, I thought the 5 mark was horrible on C3, I found out later that no one in my class knew what to say for it either!

The qustion on the last page about total volume? c3

55cm^3

maximum amount of HCl added was 30cm^3 i think... , then add that to the sodium hydroxide (25cm^3) used in the investigation.

P.S : I hate investigation questions. The reading takes alot of time.

What did people get for why Iodine had a low boiling point?

It was a simple molecular structure so it needed very little energy to overcome the weak intermolecular bonds

Hoping c3 grade boundaries are lower than last year due to this exam being so much harder! Have definitely lost all easy marks. Would love to see a mock up mark scheme if somebody has one.
