(B) The concentration of hydrogen ions $[H^+]$ is related to $pH$ by the formula: $[H^+] = 10^{-pH}$.Initially,$pH_1 = 5$,so $[H^+]_1 = 10^{-5} \ M$.Finally,$pH_2 = 2$,so $[H^+]_2 = 10^{-2} \ M$.The factor by which the concentration increases is given by the ratio: $\frac{[H^+]_2}{[H^+]_1} = \frac{10^{-2}}{10^{-5}} = 10^{(-2 - (-5))} = 10^3 = 1000$.Therefore,the hydrogen ion concentration increases by a factor of $1000$.

In a solution,$pH = 5$. Upon adding more acid,the $pH$ decreases to $2$. The hydrogen ion concentration increases by a factor of:
