Recently my frnd told me guesses (seem correct) for chemistry
Q1.Titration with KMnO4, might involve dilution using volumetric flask, and finding water of crystallisation, either of MgSO4,or CuSO4. The answer will be 7! It could be the other way round, and the salt will be XSO4.7H2O and X has to be deduced!
Theres use of a crucible involved, check Nov 2009 33 Question 1!! 31!! And 2002 year!!
Q.2 Salt analysis, possibly Ammonium sulphate, Ammonium bromide, Zinc nitrate!!!
Remember these are (almost) guesses combined with info but its the best picture for tomorrow out there
