I figured it would be
KAlSO42 aq + 4 KOH aq ----> 2K2SO4 aq + KAlOH4 aq

Which would make the net ionic equation to nothing, therefore no reaction.

But in my lab, I initally added the KOH to the Alum solution and nothing happened. But as i added more drops of KOH, percipatation formed; this boggled my mind.

Why does adding more KOH produce a reaction even though the molecular forumla and therefore, the net ionic equation state that it doesnt have a rxn. Even the physical states of the moledcular forumla states there isnt a reaction. Please explain. Thanks

The precipitate is Al(OH)₃,I think.
