I got gradient 7 too! the first part was that solubility decreases when temperature increases because equilibrium shifts to the left (Le Chatelier) right?
Also what anomalous points did you get?

Yea

I got 2 anomalies
One above the line and one below

For the one below the line I talked about incomplete heating cuz it lost too little mass
And the one above I talked about some of the sulfate being decomposed cuz it lost too much mass

Nice

What points did u put for the 8 mark question in q1

that wasn't easy, mentioned apparatus with capacity, some calculations and conclusion on how the titres could have been accurate and so on. I think i messed that up a little... what was the indicator? also the very last question of the paper was the one where we had to state the value of x and explain right?

I didn't use an indicator, I used the colour of the iodine solution as the indicator
X was the same as the gradient 7 so the formula was FeSO4.7H2O

Explanation was that gradient is same a mole ratio between water and FeSO4

Yeah! But there weren't any more part questions after that were there?
