(C) The $pH$ of a solution is defined as $pH = -\log[{H^{+}}]$.For $pH = 3$,the concentration of ${H^{+}}$ ions is $[{H^{+}}]_{1} = 10^{-3} \ M$.For $pH = 6$,the concentration of ${H^{+}}$ ions is $[{H^{+}}]_{2} = 10^{-6} \ M$.The ratio of the concentrations is $\frac{[{H^{+}}]_{1}}{[{H^{+}}]_{2}} = \frac{10^{-3}}{10^{-6}} = 10^{3} = 1000$.Therefore,the ${H^{+}}$ ion concentration is reduced by $1000$ times.

The $pH$ of a solution is increased from $3$ to $6$. Its ${H^{+}}$ ion concentration will be
