Probably something on Iodine titration. Does someone have any tips on qualitative analysis?

anyone here got variant 34?

1st quetsion is prbbly on titration manganate ion nd.,...qualitative analysis should have one cation (Zinc 2+) and two anions (sulfate 2- and bromine 1-) thts my prediction

Can you share your titration values? My supervisor and majority of my classmates got them in 22-24 range but I got it around 28.5. My readings were consistent in themselves though. 3 times they fell at around 28.5.

If you think your reading is correct but cie compares your readings with the supervisor and gives you marks according to it

My titration value was exactly 23.0 and all my classmates got them in that range :s

Ppr 31 was really easy!!!

Yeah it was! I hope we did well

I took the practical on 8th, 1st question was about Titration of KMnO4 the second question was about enthalpy change of Mg ribbon in acid and the third was salt analysis of Iron (III), Iron (II), NH4 & Mn
