Question

i'm struggling to produce a method to distinguish solutions of 9 ionic compounds labelled A-I by a series of test tube reactions. This method needs to be in a logical sequence to prevent too many test being done unnecessarily. These must be test tube reactions so no flame tests.
These are the ionic compounds
potassium iodide
potassium chloride
potassium bromide
potassium sulfate
potassium hydroxide
potassium carbonate
ammonium chloride
barium chloride
magnesium chloride
thank you
