At $25 \, ^\circ C$,the dissociation constant of a base $BOH$ is $1.0 \times 10^{-12}$. The concentration of hydroxyl ions in $0.01 \, M$ aqueous solution of the base would be:
- A$2.0 \times 10^{-6} \, mol \, L^{-1}$
- B$1.0 \times 10^{-5} \, mol \, L^{-1}$
- C$1.0 \times 10^{-6} \, mol \, L^{-1}$
- D$1.0 \times 10^{-7} \, mol \, L^{-1}$
