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
