EXOTHERMIC REACTION: HEAT PACK - REUSABLE (1 of 2)<br />
Crystallization of Solution Increases Temperature<br />
Supersaturated solution of sodium acetate is induced to crystallize by motion of a metal plate. As the salt precipitates the temperature of the solution rises to melting point of the salt (58 C). Pack is reused by heating it enough to redissolve solute.
