Question

13. In the reaction
2 NaOH+H,PO, → Na HPO,+ 2H,0, the
Equivalent weight of the acid is
1) 49
2) 98 3) 32.6 4) 36.5​

Answer 1

Explanation:

In the reaction

NaOH+H

3

PO

4

→NaH

2

PO

4

+H

2

O

Number of hydrogen ions replaced by the base of the acid is 2.

Molar mass of the acid =98gmpermol

Equivalent weight =

2

98

=49
