me again 8. You are given two beakers, A and B, with colorless liquids in htem. What two tests would you perform to determine which one is a strong acid and which one is a weak acid? Be specific with the test and the results as well as how you would determiine which is which. ...

thanx alot =)

i tried dat..n got: AlPO4(s)+H3O^+(aq)<=>Al^3+(aq)+HPO4^2-(aq) buh for sum reason its not accepting the answer

AlPO4(s)<=>Al^3+(aq)+PO4^3-(aq) PO4^3-(aq)+H3O^+(aq)<=>HPO4^2-(aq)+H2O(l) What is the net ionic equation for AlPO4(s) dissolving in H3O^+(aq)?

thanx alot =)
