Why would magnesium sulfate is give the same result (white precipitate) in the Phosphate ion test as zinc acetate? The control procedure was 2mL of .1M zinc acetate with 2 mL sodium phosphate tribasic in a test tube. Yields a white suspended precipitate immediately. The experiment was a mixture of the same sodium solution and 2mL of unknown liquid this yielded the same result immediately. I then tried to confirm my guess of the unknown liquid as magnesium sulfate by...
