It was a really mean paper. A lot of the past papers are very repetitive, they definitely tried their hardest to find the most obscure things to question on
Was a hard paper for ABG, good for me because if I don't have 100% I certainly got the A I need. The question I wasn't quite sure how to answer (as I haven't seen it before) was the question explaining the ionic lattice but I'll have to see what the mark scheme says is needed for those 2 marks.
What did people put for the ionic lattice question? I said along the lines of: Oppositely charged ions are attracted together by electrostatic forces of attraction in a ionic lattice which is cube like in structure?

Difficult compared to the past papers, but not ridiculous, mainly need the answers to the titration questions
Cant remember numbers, but one of the important things was you do 29.5 - 18 to work out the moles of the second sodium compound, making sure to times by 2 for the moles represented in the equation, then times by 8 as the question asked for moles in 200cm3 not 25cm3
I think the paper was alright if we had more time! For the ionic lattice I put: a uniform arrangement of positive and negative ions held in crystalline structure by electrostatic attraction. All anions are surrounded by only cations and all cations are surrounded by only anions
