The concentration of hydroxide ion in a ...

The concentration of hydroxide ion in a water sample is found to be `2.5xx10^(-6)M`. Identify the nature of the solution.

Text Solution

Verified by Experts

`[OH^-]=2.5xx10^(-6)M`
`pOH=-log[OH^-]`
`=-log(2.5xx10^(-6))`
`pOH=5.6021`
`PH+pOH=14`
`PH=14-5.6021`
`=9.3979`
The solution is basic.
