Question

The normality of 1MH3PO3 solution is

Answer 1

Answer:

1 mol of H

3

PO

4

gives 3 moles of H

+

ions

In Phosphoric acid (H

3

PO

4

) no. of H

+

ions it produces on dissociation per molecule of acid is 3. Hence the n-factor for phosphoric acid H

3

PO

4

is 3.

Normality= Molarity ×n−factor

=1× 3 =3 N
