$(i)$ If the value of $K_{b}$ is more than base is more strong. $(ii)$ $K_{b}$ is a dimensionless quantity.

$(iii)$ With the help of $\mathrm{K}_{b}$, calculate $\left[\mathrm{OH}^{-}ight]$of weak base and then $pOH.$ $(iv)$ The ionization degree $(\alpha)$ of base can be calculated by value of $K_{b}$.

$(v)$ $\mathrm{pK}_{b}$ is calculate by using the value of $\mathrm{K}_{b^{*}}$

$\mathrm{pK}_{b}=-\log \left(\mathrm{K}_{b}ight)$

If $\mathrm{pK}_{b}$ value is more then base is less strong.


	
		
			$\mathrm{K}_{b}$
			$1 	imes 10^{-1}$
			$1 	imes 10^{-2}$
			$1 	imes 10^{-3}$
		
		
			$\mathrm{pK}_{b}$
			$+1$
			$+2$
			$+3$
