HELP PLEASE :D coursework A2
hey all,
just need a little help,
ill give you the jist of it all:
in this experiment you are to use two methods to provide results which will enable you to calculate the formula of hydrated iron (III) sulphate crystals,
FeSo4. xH2O
the method im stuck on is with the titration
you are to weight between 2.85g and 3.10g of the iron sulphate crystals
then add 50cm3 of 1mol h2so4 and make up a 250cm3 solution in a v.flask
then pipette 25cm3 of the solution into a conical flask, add 20cm of 1mol h2so4
then titrate with 0.01mol of kmno4
i weighed 2.9g
and my titration came out at 13.6cm3
ive started the eq so far, but no luck
any help or suggestions would be great
thanks all
