What is the equivalent weight of phosphoric acid `(H_(3) PO_(4))` according to the equation
`NaOH + H_(3) PO_(4) rarr NaH_(2) PO_(4) + H_(2)O`

A

`25`

B

`49`

C

`59`

D

`98`

Text Solution

Verified by Experts

The correct Answer is:
D
Molecular weight of `H_(3)PO_(4)` is `98` and change in its valency `=1` equivalent wieght of `H_(3)PO_(4)`
`=("Molecular weight")/("change in valency")=(98)/(1)=98`
