Distinguish between the following pair of compounds using a reagent as a chemical test: Magnesium chloride and magnesium nitrate solution.

Silver nitrate can be used to test chloride ion present in a compound thus magnesium chloride reacts with silver nitrate and forms a white precipitate of silver chloride and an aqueous solution of magnesium nitrate, but magnesium nitrate does not react with silver nitrate.
