Chapter 14, Problem 61E

Determine if each solution is acidic, basic, or neutral.

a. $\left[{\text{H}}_3{\text{O}}^{+}\right]=1\times {10}^{-5}\text{M;}\left[{\text{OH}}^{-}\right]=1\times {10}^{-9}\text{M}$

b. $\left[{\text{H}}_3{\text{O}}^{+}\right]=1\times {10}^{-6}\text{M;}\left[{\text{OH}}^{-}\right]=1\times {10}^{-8}\text{M}$

c. $\left[{\text{H}}_3{\text{O}}^{+}\right]=1\times {10}^{-7}\text{M;}\left[{\text{OH}}^{-}\right]=1\times {10}^{-7}\text{M}$

d. $\left[{\text{H}}_3{\text{O}}^{+}\right]=1\times {10}^{-8}\text{M;}\left[{\text{OH}}^{-}\right]=1\times {10}^{-6}\text{M}$
