13. Consider a $50\mathrm{mL}$ solution of $0.150{\mathrm{MNH}}_3\left(K_{\mathrm{b}}=1.8\times 10^{-5}\right)$. You are titrating it with a solution that is $0.120\mathrm{MHClO}$. a) Find the $\mathrm{pH}$ of the solution after the addition of $15\mathrm{mL}$ of $\mathrm{HClO}$. b) Find the $\mathrm{pH}$ of the solution at the one-half equivalence point. c) Find the $\mathrm{pH}$ of the solution at the equivalence point. d) Find the $\mathrm{pH}$ of the solution after the addition of $70\mathrm{mL}$ of $\mathrm{HClO}$.
