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 = 5 xx 10^(-2) . (mol)/L `
`pOH = - log [OH^(-)] = - log [ 5 xx 10^(-2)] `
` pOH = 1.30 , pH + pOH = 14 `
`pH = 14 - pOH = 14 - 1.30 = 12.7`
