Why is a precipitate shown with a downward arrow?

Answer and explanation

Correct answer: It separates as an insoluble solid

In chemical equations, a downward arrow is used to mark a precipitate. A precipitate is a solid product that forms from a solution and does not dissolve appreciably in the solvent, so it separates and settles. The symbol therefore communicates the physical state and separation of the product. A gas would be indicated by an upward arrow, while heat and light are not represented by this notation.
