A base dissolved in water yields a solution with a hydroxide ion concentration of `0.05 mol litre^(-1)`. The solution is

A

basic

B

acid

C

neutral

D

both (`a`) and (`b`)

Text Solution

Verified by Experts

The correct Answer is:
A
`[OH^(-)]` ion conc. `=0.05(mol)/(L)=5xx10^(-2)(mol)/(L)`
`pOH= -log[OH^(-)]= -log[5xx10^(-2)]`
`pOH=1.30` , `pH=pOH=14`
`pH=14-pOH=14-1.30=12.7`
