Question

If you are a given a salt .How do you identify its nature?

Answer 1

Answer:

Table salt which is sodium chloride is no an acid or basic. But a salt, as it is formed by the replacement of the H++ ion in hydrochloric acid by sodium ion. Ifit is basic, the indicator will turn blue but it will turn green as salts. 

Answer 2

We can make a solution of the salt and water. After that we can use a litmus paper. If a blue litmus paper turns red it's an acidic salt. If the red litmus paper turns blue it is a basic salt.
