SOLVED:Novocaine, \mathrm{C}_{13} \mathrm{H}_{21} \mathrm{O}_{2} \mathrm{N}_{2} \mathrm{Cl} , is the salt of the base procaine and hydrochloric acid. The ionization constant for procaine is 7 \times 10^{-6} . Is a solution of novocaine acidic or basic? What are \left[\mathrm{H}_{3} \mathrm{O}^{+}\right],\left[\mathrm{OH}^{-}\right], and pH of a 2.0\% solution by mass of novocaine, assuming that the density of the solution is 1.0 \mathrm{g} / \mathrm{mL}
