Question

identity one catonic radical in the given unknown inorganic salt M1 by performing dry wet and wet test
​

Answer 1

Answer:

Salt analysis (also known as systematic qualitative analysis or qualitative inorganic analysis) involves the identification of the cation and anion of an inorganic salt. This is done by conducting a series of tests in a systematic manner and using the observations to confirm the absence or presence of specific cations and anions. Salt analysis is an integral part of the CBSE Class 12 Chemistry practical examinations and is a topic that several students struggle with. Therefore, we at BYJU’S have channelled our efforts into explaining this topic in a manner that is easy to understand and remember. If questions like “How to do salt analysis?” and “How to remember salt analysis procedures easily?” are puzzling you, look no further! This article also touches on certain tricks and shortcuts that students can employ to quickly analyze their assigned salts in their chemistry practical examinations.

Answer 2

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

Explanation:

Identification of cationic radical by DRY Test :-

1. It involves the physical examination of the dry salt
2. A Study of colour, the smell is done to identify the salts.
3. Characteristics smell of the ions helps in the identification of salts.

Identification of cationic radical by WET Test

The test involves the following steps:-

1. A Clear and transparent solution is prepared using salt. This solution is known as the original solution.
2. Preparation of original solution-
3. 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.
4. If the salt is insoluble in water then we take fresh salt in a clean tube and add a few drops of  the salt does not dissolve in cold heat the solution till the salt is completely dissolved.

1. If the salt does not dissolve in water, dil HCl and even on heating it is further added with conc HCl and then heated.
2. If the salt does not dissolve in Conc HCl then we dissolve the salt in dilute nitric acid.
3. 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.
4. This mixture of nitric acid and hydrochloric acid in the ratio of 1:3   is called aquaregia.
5. Salt which does not dissolve in aquaregia is termed an insoluble salt.
