Rate of Solution Demonstration

Add to list Go to activity
In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid. Learners will compare how crushing sugar cubes, stirring and water temperature affect the rate at which the sugar dissolved. This resource guide includes extensions and notes about factors that accelerate dissolution and Henry's Law.
