Question

Match the following:

Column A	Column B
(i) Acid salt	(A) Ferrous ammonium sulphate
(ii) Double salt	(B) Contains only ions
(iii) Ammonium hydroxide solution	(C) Sodium hydrogen sulphate
(iv) Dilute hydrochloric acid	(D) Contains only molecules
(v) Carbon tetrachloride	(E) Contains ions and molecules

Answer 1

Hint: In this question, the properties and the nature of the compounds are given. The ionic compounds are those which are formed of ions and joined together by ionic bonds. The covalent compounds are those where the atoms are joined by covalent bonds. Salt which is formed of strong acid and weak base is known as acid salt.

Complete step by step answer:
Acid salt are those which on dissolving in water forms acidic solution.The example of acid salt is sodium hydrogen sulphate. Sodium hydrogen sulphate is also known as sodium bisulfate which is formed from the neutralization reaction of strong acid sulfuric acid and equivalent of sodium hydroxide. When sodium hydrogen sulphate is dissolved in water, it forms an acidic solution.
Double salt is a type of salt which contains one or more than cation or anion.The example of double salt is ferrous ammonium sulphate. Ferrous ammonium sulphate is also known as Mohr’s salt which is formed of two salts one is ferrous sulphate and other is ammonium sulphate.
The ammonium hydroxide is a weak base which does not completely dissociate into its constituent ions. It contains both ions and molecules.
Dilute hydrochloric acid is a strong acid which completely dissociates into its constituents ion. Hydrochloric acid forms hydrogen ion and chloride ion. Therefore, it contains only ions.
Carbon tetrachloride is a covalent compound, therefore it contains only molecules.
The correct match is shown below.
$(i) \to C,(ii) \to A,(iii) \to E,(iv) \to B,(v) \to D$

Note: Ferrous ammonium sulfate and sodium hydrogen sulfate both are salts which are formed by the neutralization reaction of acid with a base but they differ in their composition of compounds.
