Question

Is a solution with a pH of 10 more basic than a solution with pH 8? Why so?

Answer 1

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?
