Na3PO4, KI and AlCl3, respectively. These results were found by using a Universal Indicator. I have to write out a net ionic equation to explain my observations for these 3 solutions, but obviously i do not know how to do this.

Please, any help would be greatly appreciated, thanks!!!

Na3PO4 ===> Na+ + H2PO4- + OH-

or they may want Na3PO4 + 3H2O ===> 3Na+ + PO4 3- + 3OH-

KI ===> K+ I-

AlCl3 + H2O ===> Al(OH)3 + 3H+

The first solution will test basic because of the OH- generated. The KI solution will test neutral. The third solution will test acid.
