In the reaction, $H_{3} PO_{4} + Ca (OH)_{2} ⟶ CaHPO_{4} + 2 H_{2} O$ , the equivalent weight of $H_{3} PO_{4}$ is

Answer:

Solution:

$n$ -factor of H₃PO₄ = 2 because, out of 3 moles of H⁺ present in 1 mole of H₃PO₄, only 2 moles have been replaced.

Therefore, the equivalent weight of H₃PO₄ = $\frac{98}{2} = 49$
