One litre of water contains `10^(-7)` mole `H^(+)` ions. Degree of ionisation of water is:

A

`1.8xx10^(-7) %`

B

`0.8 xx 10^(-9) %`

C

`3.6 xx 10^(-9) %`

D

` 3.6 xx 10^(-7) %`

Text Solution

Verified by Experts

The correct Answer is:
A
1L of water has `(1000)/(18)` moles
Thus `alpha=((10^(-7))/(1000))/(18)=1.8 xx 10^(-7)%`
