You are provided with the following chemicals:

NaOH, Na₂CO₃, H₂O, Zn(OH)₂, CO₂, HCl, Fe, H₂SO₄, Cl₂, Zn

Using suitable chemicals from the given list only, state briefly how you would prepare:

(a) Iron(III) chloride, (b) Sodium sulphate,

(c) Sodium zincate, (d) Iron(II) sulphate,

(e) Sodium chloride ?

Answers:

(a) Preparation of Iron (III) Chloride – Iron chloride is formed by direct combination of elements.

Reaction Involved: 2Fe + 3Cl₂ → 2FeCl₃

(b) Preparation of Sodium sulphate – By neutralization of caustic soda with dilute sulphuric acid

Reaction Involved: 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O

(c) Preparation of Sodium zincate – By the action of metals with alkalis

Reaction Involved: Zn + 2NaOH → Na₂ZnO₂ + H₂

(d)Preparation of Iron (II) sulphate – Iron sulphate is prepared by the action of dilute acid on an active metal.

Reaction Involved: Fe + H₂SO₄→ FeSO₄ + H₂

(e)Preparation of Sodium chloride – By the neutralization reaction of a strong acid with a strong base

Reaction Involved: NaOH + HCl → NaCl + H₂O
