i got 0.0005 moles
i even did it with the concentration that they gave it to us ! i got the same points

I also got same concentration! YIPEE...

I got the graph as a straight line, all points were close to it and it passed through the origin. Concentration of iodine was 0.0005. The time in the last part (g) was 73s.

For salt analysis:
FA5 was Copper(II)Chloride
FA6 was NaOH
FA7 was Lead ion
FA8 was Chromate ion
FA9 was Sulfate ion (SO4)

woohhoo!! got all of them right!

Hi ppl .... wat if some1 makes a wrong observation and deduces the salt according to their own observation ???? Do they get the error carried forward mark

This chemistry paper was way too similar to M/J 07 v2. In order to practice for these nerve-wracking practical exams, you might like to go through some past papers and visualize yourself doing the practical. But if you didn't miss your lab classes, it wouldn't be much of a problem. And of course, you must check the mark schemes. Be careful about significant figures, line of best fit, choosing an appropriate scale for plotting results etc. One last thing, when you get the paper, don't such rush it out---understand the question and then put your best foot forward. Plus, do check out the examiner tips on the cie website. Sorry if I sound too preachy! Good Luck...
