NH3 is a weak base, NaOH is strong base. Predict what would appear in a soln if NaOH were added to CuSO4 solution instead of NH3.
Sleeping pills often contain barbital, which is weakly acidic (pKa = 8.00). For analysis of the barbital content of a sleeping pill, a titration is carried out with strong base. It takes 12.00 mL of 0.200 M base to reach the stoichiometric point.
