What does a downward arrow show in a chemical equation?
Answer and explanation
Correct answer: Formation of a precipitate
In a chemical equation, a downward arrow (↓) commonly indicates that an insoluble solid has formed and settled out of a solution. This solid is called a precipitate, so option B is correct. A gas is usually shown by an upward arrow (↑), whereas heat and light are indicated by words or suitable symbols rather than by a downward arrow.
