One mole of `P_(2)O_(5)` undergoes hydrolysis as
`P_(2)O_(5) +H_(2)O to H_(3)PO_(4)`
The normality of the phosphoric acid formed is (Volume of the solution is 1L)

Text Solution

Verified by Experts

The correct Answer is:
D
b) `2P_(2)O_(5) + 6H_(2)O to 4H_(3)PO_(4)`
`therefore` 1 L solution contains 4 moles of `H_(3)PO_(4)`.
`therefore` molarity of `H_(3)PO_(4)` = 4M
Normality = Molarity x Basicity = `4 xx 3N = 12N
=10/10 xx 1000/100 = 2.5 m
