Volume (in ml) of 0.7 M NaOH required for complete reaction with 350 ml of o.3 M `H_(3) PO_(3)` solution is

A

300 ml

B

450 ml

C

150ml

D

350ml

Text Solution

Verified by Experts

The correct Answer is:
A
`2NaOH+H_(3)PO_(3)to Na_(2)HP_(3) +2H_(2)O(l)`
350 x 0.3
mm NaOH=2 x 350 x 0.3
Vx0.7=2 x 350 x 0.3
V= 300 ml
