Answer:

In aqueous solution, #pH=-log_10[H_3O^+]# by definition, and so............

Explanation:

And thus if #pH=10#, by definition, #[H_3O^+]=10^(-10)*mol*L^-1# with respect to #H_3O^+#.

And if #pH=8#, by definition, #[H_3O^+]=10^(-8)*mol*L^-1# with respect to #H_3O^+#.

And thus a solution that is #[H_3O^+]=10^(-10)*mol*L^-1# with respect to #H_3O^+# is a hundredfold LESS concentrated than when #[H_3O^+]=10^(-8)*mol*L^-1#. Capisce?
