Some substance, as a result of interaction with a solution of silver nitrate, forms a dark-colored precipitate.

Some substance, as a result of interaction with a solution of silver nitrate, forms a dark-colored precipitate. Write down the possible formula of the substance and write the equation for the corresponding reaction.

Explanation of the solution to the problem: a white precipitate with silver nitrate (or rather with a silver cation) can form a chlorine anion, so this substance can be any water-soluble chlorine salt, for example sodium chloride NaCl.
NaCl + AgNO3 = AgCl (precipitate) + NaNO3.
