Dissolving Ionic Salts in Water Demonstration
Several ionic salts (calcium chloride, ammonium nitrate, potassium chloride, magnesium sulfate, lithium chloride, anhydrous sodium acetate, anhydrous sodium carbonate) are dissolved in water in a calorimeter. A thermometer measures the initial temperature of the water and the final temperature of the resultant solution. Dissolving ionic salts in water can be used to illustrate formation of Solutions, Enthalpy, Lattice Energy, etc.
Curriculum Notes
A short computer animation illustration how positive and negative ions in a solid ionic compound dissolve in water might be used to accompany dissolving salts in water lecture demonstration.
Lead Time
One day of lead time is required for this project.
