Question

salt analysis of chloride

Answer 1

Answer:

Qualitative analysis of a salt Analysis is a chemical technique used to identify the ions present in a salt by analyzing its physical and chemical properties and hence determine the identity of the salt.

It determines only the presence or absence of a particular ion in a given salt. This method does not determine how much of a particular ion is present.

For example, a student did a chemical analysis on a sample of salt X. His results showed the presence of sodium ions and bromide ions. His conclusion was the salt must be sodium bromide.

Explanation:

The procedure for testing salts in the laboratory consists of the following general steps.

1. Make initial observations of the physical properties of the salt.
2. Study the action of heat on the salt.
3. Make an aqueous solution of the salt to test for anions and cations present.
4. Carry out confirmatory tests for cations and anions.
