Solution

The correct option is D 0.0003 M
$C = 0.01 M$

As $N H_{3}$ is a base,

$[O H^{-}] = C α$

$α = 3$ %

$[O H^{-}] = 0.01 \times \frac{3}{100} = 0.0003 M$

A 0.01 M ammonia solution is 3% ionised. The concentration of OH− ion:

The correct option is D 0.0003 MC=0.01 MAs NH3 is a base,[OH−]=Cαα=3%[OH−]=0.01×3100=0.0003 M
