Seema Saini Solutions for Chapter: Ionic Equilibrium, Exercise 1: DPP 7.1

The increasing order of base strength is

The decreasing base strength of ${\mathrm{OH}}^{-},{\mathrm{NH}}_2^{-},\mathrm{HC}\equiv {\mathrm{C}}^{-}$ and ${\mathrm{CH}}_3{{\mathrm{CH}}_2}^{-}$ is

$\mathrm{BOH}$ is a weak base. The molar concentration of $\mathrm{BOH}$ that provides an $\left[{\mathrm{OH}}^{-}\right]$ of $1.5\times {10}^{-3} \mathrm{M}$ is

$\left[{\mathrm{K}}_{\mathrm{b} }\left[\mathrm{BOH}\right]=1.5\times {10}^{-5} \mathrm{M}\right]$
