Answer 2

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

Explanation:

Identification of cationic radical by WET Test

The test involves the following steps:-

• A Clear and transparent solution is prepared using salt. This solution is known as the original solution.

Preparation of original solution

• A little amount of salt is used in a clean boiling tube and a few drops of distilled water is added and then it is shaken.  If the salt is not dissolved it is allowed to heat so that the salt gets dissolved.
• If the salt is insoluble in water then we take fresh salt in a clean tube and add a few drops of the salt do not dissolve in cold heat the solution till the salt is completely dissolved.
• If the salt does not dissolve in water, dil HCl, and even on heating it is further added with conc HCl and then heated.
• If the salt does not dissolve in Conc HCl then we dissolve the salt in dilute nitric acid.
• If the salt does not dissolve in dilute nitric acid then a mixture of nitric acid and hydrochloric acid is added in the ratio of 1:3.
• This mixture of nitric acid and hydrochloric acid in the ratio of 1:3   is called aquaregia.
• Salt which does not dissolve in aquaregia is termed an insoluble salt.
