1.A. Suppose the weak diprotic acid, hydrogen sulfide (H2S), is titrated with KOH solution. What is the charge balance equation, representing all charged species present, once the titration is started? **I assumed it would be an acid balance with H2O as a biproduct but it still didn’t seem to get the correct score** please let me know how to properly solve this. 1.B An aqueous solution is formed by dissolving 0.20 moles of sodium sulfide (Na2SO3) in 1.0 L of...
