Question

Identify anion in solution 'X' when mixed with barium nitrate which gives white ppt.​

Answer 1

Answer:

The anion in solution 'X' should be sulphate ion.

Explanation:

when sulphate ion reacts with barium nitrate, it produces barium sulfate solid which is white in color.

The solution must be MSO_4MSO

, where, M is a metal other than barium.

Reaction between X and BaNO_3BaNO

3

follows the equation:

MSO_4+BaNO_3\rightarrow BaSO_4+M(NO_3)_2MSO

4

+BaNO

3

→BaSO

4

+M(NO

3

)

2

This reaction is double displacement reaction, where exchange of ions takes place.
