Answer:
NaOH + H3PO4 ----------> NaH2PO4+ H2O
We know that for the Acids, the equivalent weight is equal to the ratio of the molar mass and number of the hydrogen ions of the acid accepted by the base.
∴ In the given reaction,
No. of hydrogen ions replaced by the Base of the Acid = 2
Molar mass of the Acid = 98 g/mole.
∴ Equivalent Weight = 98/2
= 49
Hence, the equivalent weight of the Acid is 49.
