    Lets say you were given an unknown which contains two salts, and your results give you evidence that potassium phosphate, ammonium, and carbonate ions are all present. What are four possible salts that could be your unknown?

    Nope.

    Salt contains a cation and an anion. You have two cations and two anions. In how many ways can you combine them?
