Saturated, Unsaturated, and Supersaturated Solutions
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A solution is saturated at its solubility limit, unsaturated below it, and supersaturated above it in an unstable, nonequilibrium state.
Show
A hand warmer's sodium acetate solution stays supersaturated until disturbed, then rapidly precipitates the excess and releases heat.
Watch for
A supersaturated solution is not at equilibrium and can be disturbed into sudden precipitation of its excess solute.
