An unstable solution containg more than the maximum amount of didolved solute is a saturated solution?

An unstable solution containing more than the maximum amount of dissolved solute is referred to as a supersaturated solution, not a saturated solution. A saturated solution has dissolved the maximum amount of solute that can be held at a given temperature and pressure, while a supersaturated solution temporarily holds more solute than is normally possible. This condition is unstable, and the excess solute can precipitate out if disturbed or if conditions change.
