What is the n-factor for `H_(3)PO_(4)` in the reaction `2NaOH+H_(3)PO_(4)rarr Na_(2)HPO_(4)+2H_(2)O`?

Text Solution

Verified by Experts

Valency factor of base = 1
Here, one of molecule of `H_(2)SO_(4)` replaced one `OH^(-)` from NaOH. Therefore, valency factor for `H_(2)SO_(4)` is one
`:. ` Eq. wt. of `H_(2)SO_(4)=("Mol.wt")/(1)`
