In the reaction, $H_{3} P O_{4} + C a (O H)_{2} \to C a H P O_{4} + 2 H_{2} O,$ the equivalent mass of $H_{3} P O_{4}$ is

Options:

Answer:

Solution:

In the reaction
$H_{3} P O_{4} + C a (O H)_{2} \to C a HP O_{4} + 2 H_{2} O,$
Basicity of phosphoric acid is 2.
Thus, equivalent mass of $H_{3} P O_{4} = \frac{M o l e c u l a r m a s s}{B a s i c i t y}$
$= \frac{98}{2} = 49 g$ .
