The ⇌ symbol, formally known as the Rightwards Harpoon Over Leftwards Harpoon, is primarily used in chemistry to denote a reversible reaction or chemical equilibrium. In Unicode, it belongs to the arrows block and visually consists of two stacked half-arrows pointing in opposite directions. Beyond science textbooks, you might spot it in technical documentation to illustrate bidirectional processes or a state of physical balance.
