chem p33 final!!

[deelo]

The best possible info i can give u guys is that there is NO titration in the paper tomorrow!!!
there is a question regarding the heat of reaction..two salts SODIUM SULPHATE AND SODIUM CARBONATE will be provided, we will hv to find out the change in temp, there will b a question regarding the enthalpy change of the reaction!!
another question will be about the identification of anions and cations!!
5salts, CuSO4, MnSO4, CoCl, NH4Cl will be provided..
cations are Cu, Mn, NH4
anions are SO4 and Cl

This is all the information i got.. It is strongly recommended that u perform the practical.. There is always a possibility that the reagents or the conc. of solutions are changed before the examination!!!

GOOD LUCK PEOPLE..!!!
