Question

Identify one cationic radical in the given unknown inorganic salt 'M' by performing dry and wet test.
​

Answer 1

Cationic  radicals of inorganic salts are identified with the help of Dry and wet test of the salts.

Explanation:

Identification of cationic radical by dry test :-

• In this small amount of salt is used and is observed for colour, small moisture.

• The temperature should be room temperature at which the study is done.
• Carbonate, sulphide, sulphite, nitrite and acetate reacts with sulphuric acid to evolve various gases.
• The evolved gases is studied to collect the information of anionic radicals.

Identification of cationic radical by WET Test

• A Confirmatory test of anions is carried out by dissolving in water. It is soluble in water and then using sodium carbonate extract.

• Using sodium extract the confirmatory test of anions is done.
