Vedclass · Answer

(D) The $pH$ of a solution is defined as the negative logarithm of the hydronium ion concentration,i.e.,$pH = -\log [H_3O^{+}]$.Since $-\log [H_3O^{+}] = \log \frac{1}{[H_3O^{+}]}$,option $B$ is also correct.By rearranging $pH = -\log [H^{+}]$,we get $[H^{+}] = 10^{-pH}$,which is also a valid representation of the relationship.Therefore,all the given equations represent the $pH$ of a solution correctly.
