what if in the 3 mark anomaly question i chose two of the 4 anomalies that i got and i explained those 2 only, would i lose marks then

If all four of your points were on the same side of the graph then you only had to give reason for the anomaly furthest from the line of best fit.
If you had points on both sides of the line then you had to pick points furthest from the line on each side and the give a reason for each of those point. You are not required to give a reason for all 4 points.

Mine attempt was not good too, May Allah ease it on us
lol realized the fact of 1g solubility after announcement of 5 mins remaining
what a good luck!!
and lol i started to attempt planning just when panic time starts around 7 mins before
and left few points May Allah help me on this!
mine Q2 graph was also not a straight line after i was getting moles of crystal in x10-2 dp
so i drawed a curve after a straight line
pretty sure examiner gonna laugh
and got 6 as a gradient..

I used c1v1 = c2v2 too.
I changed the value of HCl's conc.
Made a small graph showing 2, 1.8, 1.6 and so on values.
I did blunders in this part. :s

Hey guys! How did you guys drew the graph of Q1?

I hope you guys are talking about variant 2.. Am I right? :cry:
Because our paper didn't have any dilutions to be made... (variant 1)
