QUESTION 9 Consider the dissolution of MnS in water (Kp = 3.0x10-14). MnS(s) + H20() Mn2 (aq) + HS-(aq) + OH-(aq) How is the solubility of manganese(Il) sulfide affected by the addition of aqueous potassium hydroxide to the system? Oa. The solubility will increase. Ob. The pK, of H,S is needed before a reliable prediction can be made. Oc. The amount of KOH added must be known before its effect can be predicted Od The solubility will be unchanged. Oe. The solubility will decrease.
