    Al(OH)2 ==>Al^+2 + 2OH^- but that doesn't tell me much. I don't know what Al(OH)2 is. There is a Al(OH)3; i.e., aluminum oxide.

    No! It Al(OH) with the subindex of 2 ==> Al to the power+ plus OH with a negative sign on the top!

    Then it is balanced correctly if the -- you have is an arrow --> and not two minus signs.
