8 g of sulphur is burnt to form SO2 which is oxidized by Cl2 water The solution is treated with BaCl2 solution The amount of BaSO4 precipitated is

A/ I mole
B/ 0.5 mole
C/ 0.24 mole
D/. 0.25 mole
Which option is correct??

1 answer

S + O2 ==> SO2
SO2 + Cl2 ==> SO4^2-

mols S = grams/atomic mass = ?
1 mol S = 1 mol SO4^2-
1 mol SO4^2- = 1 mol BaSO4
I believe that is D
