Give the preparation of the salt shown in the left column by matching with the methods given in the right column. Write a balanced equation for each preparati Salt Method of preparation Zinc sulphate Precipitation Ferrous sulphide Oxidation Barium sulphate Displacement Ferric sulphate Neutralisation Sodium sulphate  synthesis

Answer»

Zinc Sulphate – Displacement

Zn(OH)2 + H2SO4 ⟶ ZnSO4 + 2H2O

Ferrous sulphide – synthesis

Fe + S ⟶ FeS

Barium sulphate – Precipitation

BaCI2+H2SO4 ⟶ BaSO4 + 2HCI

Ferric sulphate – Oxidation

Fe + H2SO4 ⟶ FeSO4 + H2

Sodium sulphate – Neutralisation

2NaOH + H2SO4 ⟶ Na2SO4 + 2H2O
