Rapid Crystallization (Supersaturated Solution Demo)


Video powered by Metacafe

A seed crystal is dropped into an unstable supersaturated solution of sodium acetate NaC2H3O2 and it completely crystallized in front of your eyes. This chemistry more...

demonstration is prepared by heating 700 grams of sodium acetate in 50mL of water in a flask until all the solid dissolves. The solution is then cooled back to room temperature. Drop a seed crystal and see the very cool results.
