The concentration of either the $\mathrm{H}^{+}$ ion or the $\mathrm{OH}^{-}$ ion is given for four aqueous solutions at 298 $\mathrm{K}$ . For each solution, calculate $\left[\mathrm{H}^{+}\right]$ or $\left[\mathrm{OH}^{-}\right] .$ State whether the solution is acidic, basic, or neutral. \begin{equation} \begin{array}{ll}{\text { a. }\left[\mathrm{H}^{+}\right]=1.0 \times 10^{-13} M} & {\text { c. }\left[\mathrm{OH}^{-}\right]=1.0 \times 10^{-3} \mathrm{M}} \\ {\text { b. }\left[\mathrm{OH}^{-}\right]=1.0 \times 10^{-7} M} & {\text { d. }\left[\mathrm{H}^{+}\right]=4.0 \times 10^{-5} \mathrm{M}}\end{array} \end{equation}
