First slide

Ionization constants of weak bases, PH of weak bases

Question

Which of the following relations is correct?

Easy

A

${pK}_{b} = \log (K_{b})$
B

${pK}_{b} = - \log (K_{b})$
C

${pK}_{b} = \ln (K_{b})$
D

${pK}_{b} = - \ln (K_{b})$

Solution

The pH scale for the hydrogen ion concentration has been extended to get ${pK}_{b} = - \log (K_{b})$ .
Where, K _b = Base dissociation constant.
