3. Quinine, C2H2,N2O2(aq), is responsible for saving thousands of lives during
the construction of the Panama Canal. Quinine is a weak base.
a) Write the products for the reaction below AND write the equilibrium constant expression for the reaction.
C20H2,N,O2(aq) + H,O(1)
K, =.
b) Given the value of K, for the above reaction is 8.1 x 10°, a saturated solution of quinine has a pH of 10.04.
Determine the mass of quinine that would be dissolved in a 150 mL saturated solution of quinine.
