The equivalent weight of phosphoric acid...

The equivalent weight of phosphoric acid `(H_(3)PO_(4))` in the reaction `NaOH+H_(3)PO_(4) rarr NaH_(2)PO_(4)+H_(2)O` is

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`
