Chapter 15, Problem 15.67SP

For each of the following solutions, calculate [ ${\text{OH}}^{-}$ ] from [ ${\text{H}}_{\text{3}}{\text{O}}^{+}$ ], or [ ${\text{H}}_{\text{3}}{\text{O}}^{+}$ ] from [ ${\text{OH}}^{-}$ ]. Classify each solution as acidic, basic, or neutral

(a) [ ${\text{H}}_{\text{3}}{\text{O}}^{+}$ ] = $2.5\times \text{1}{0}^{-4}$ M

(b) [ ${\text{H}}_{\text{3}}{\text{O}}^{+}$ ] = 2.0 M

(c) [ ${\text{OH}}^{-}$ ]= $5.6\times \text{1}{0}^{-9}$ M

(d) [ ${\text{OH}}^{-}$ ] = $1.5\times \text{1}{0}^{-3}$ M

(e) [ ${\text{OH}}^{-}$ ] = $1.0\times \text{1}{0}^{-7}$ M
