What is the percentage concentration of ephedrine $\mathrm{HCl}$ required to make an isotonic solution?
To prepare 30 mL of a 1% isotonic solution of procaine hydrochloride (E = 0. 21), how many grams of NaCl is needed? (by E value method)
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 $\mathrm{g} / \mathrm{mL}$
