Working with six reactant solutions come up with reactions? like potium hydroxide, silver I nitrate?

go through the cation one by one and check if it form an insoluble compound with any of the anions. ie if you mix silver nitrate and iron chloride you will get insoluble silver chloride (not sure of iron nitrate is soluble) another is if you mix iron chloride and potium hydroxide, you will form insoluble iron hydroxide and the potium and chloride ions will stay in solution. test every combination and you'll get your answer
