    Please help? I know the solution will be acidic because Kb of acetate > Ka of Al(H2O)6^3+, but I don't understand why you would even compare the Kb with the Ka 3. When dissolved in water, will aluminum acetate produce an acidic, basic, or neutral solution? Explain. Ka for Al(H20)63+ = 1.4 x 10-5 Ka for HC2H302 = 1.8 x 10-5

    Writing polyprotic acid and base reactions: 1. Write all the dissociations for the three polyprotic acids: H_2CO_3, H_3AsO_4, H_3PO_4. Match the appropriate Ka1, Ka2, Ka3 values to the dissociation reaction. 2. Identify all the species in each of the reactions as either an acid, a base, or amphoteric. Imagine putting NaH_2AsO_4 in solution. This is a salt. Describe, using chemical equation, exactly what happens? First write the dissociation reaction of the salt. Then identify the pH active species, and then...
