2. The [OH] of a 0.200 M solution of a weak acid HA is 5.0 x 10-10 M. What is the acid- ionization constant of HA? 3. Morphine is a weak base. The aqueous ionization of morphine can be indicated as: M(aq) + H₂O = MH*(aq) + OH(aq) What mass of morphine is needed to prepare 600 cm³ of a solution with a pH of 11? Note: Molar mass of morphine = 285.3 g.mol-¹. 4. Cocaine is a weak base, and the aqueous ionization can be indicated as: C(aq) + H₂O CH*(aq) + OH(aq) In a 0.0040 M solution of cocaine, the ratio of OH(aq) ions to cocaine molecules is 1.0/120. What is the value of Kb for cocaine? 2. The [OH] of a 0.200 M solution of a weak acid HA is 5.0 x 10-10 M. What is the acid- ionization constant of HA? 3. Morphine is a weak base.
