3. F. From E catergories chloride salts, nitrate salts and sulphates salts using formula
Chloride salts Nitrate salts Sulphate salts
G. The above salts are all soluble in water. Therefore soluble salts can be prepared by 4 methods
( refer to A ). All nitrate salts are soluble in water.
H. Name and write the formulae of all the insoluble salts for chlorides, sulphates and carbonates.
Chlorides Sulphates carbonates

All carbonates are insoluble
except carbonates of group 1,
that is Li2CO3, Na2CO3,
K2CO3...
I. Insoluble salts can be prepared by precipitation or double decomposition method. The reactants
are 2 aqueous soluble salts mix together to form 2 salts, soluble and insoluble salt.
