One litre of water contains `10^(-7) "moles of " H^(+) ` ions . Degree of ionisation of water (in percentage ) is

A

`1.8 xx 10^(-7) `

B

` 1.8 xx 10^(-9)`

C

` 3. 6xx 10^(-7)`

D

` 3. 6 xx 10^(-9) `

Text Solution

Verified by Experts

The correct Answer is:
A
1 lt `H_2O = 55.5 ` moles
` alpha % =( 10^(-7))/( 55.5 ) xx 100 = 18 xx 10^(-8) = 1.8 xx 10 ^(-7) `
