Question

what is normality of 0.2 M H3PO4 solution

Answer 1

2.0 mol h3po4/1ls x3eqwt h3po4/mol h3po4 =6eqwt=6.0n d. is correct

Answer 2

The normality of 0.2 M $H_{3} PO_{4}$ solution 0.6 N.

Given:

The molarity of $H_{3} PO_{4}$ solution is 0.2 M.

To Find:

The normality of the solution.

Solution:

$H_{3} PO_{4}$ is tribasic acid

The number of hydrogen ions (H+ ) is 3.

Thus basicity of $H_{3} PO_{4}$ is 3.

Normality= Basicity × Molarity

N= 3 × 0.2 = 0.6

Therefore, the  normality of 0.2 M $H_{3} PO_{4}$ solution is 0.6 N.
