(b) (c) (d) What kind of salt is prepared by precipitation? Name a salt prepared by direct combination. Write an equation for the reaction that takes place in preparing the salt you have named. Name the procedure used to prepare a sodium salt such as sodium sulphate. 4.

Dear Student,

(a) Salt : Salt is defined as the product formed along with water when an acid reacts with a base. The reaction between an acid and a base forming salt is known as neutralisation reaction.  The general equation for the neutralisation reaction is represented as:

Acid + Base → Salt + Water

For example, when sodium hydroxide (NaOH) is treated with hydrochloric acid (HCl), then a salt, sodium chloride (NaCl) and water (H O) are obtained. The chemical equation for the is given as:

 NaOH + HCl → NaCl + H2O

(b) Insoluble salts are prepared by precipitation.

(c) Iron (III) chloride or Ferric chloride

2Fe (heated) + 3Cl2 (dry) → 2FeCl3

(d) Sodium salt is produced by neutralizing sodium carbonate or sodium hydroxide with dilute sulphuric acid :

Na2CO3 + H2SO4 → Na2SO4 + H2O + CO2 
2NaOH + H2SO4 → Na2SO4 + 2H2O
