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

A

`1.8xx10^(-7)`

B

`1.8xx10^(-9)`

C

`3.6xx10^(-7)`

D

`3.6xx10^(-9)`

Text Solution

Verified by Experts

The correct Answer is:
A
`alpha%=("No.Of ionised ions" xx100)/("Total no. of molecules")`
`=(18xx10^(-7)xx6.023xx10^(23)xx100)/(1000xx6.023xx10^(23))`
`=1.8xx10^(-7)`
