They are both fine white powder type crystals with high Mp's so I would go with density or molar mass. The molar mass of strontium chloride is 158.53 (anhydrous, and up to 266.62g/mol at it's most hydrated) and of potassium chloride is 74.55g/mol. You could so a density test but for that you must make sure to use the anhydrous form. I believe the density of strontium chloride is 3.05g/cm3 (when it is anhydrous) and potassium chloride is 1.98g/cm3. The problem with this is if stontium chloride's density can be recorded as low as 1.93 depending on how hydrated it is so in order to this accuratedly you must use the anhydrous form.
