Question

Calculate the $H_3{O}^{+}$ ion concentration of a solution having a $pH$ of $10.6$.

Answer 1

$\left[H_3{O}^{+}\right]={10}^{-P^H}$

Given $pH=10.6$

$\therefore \left[H_3{O}^{+}\right]={10}^{-10.6}$

$\left[H_3{O}^{+}\right]=2.5118\times {10}^{-11}$

$\left[H_3{O}^{+}\right]=2.51\times {10}^{-11}$
