Lab-Aids: Hydrolysis of Salts Experiment Kit
Students discover how and why salts vary in neutrality, as they determine the actual acid or base makeup of different salt solutions. Using the LAB-AIDS‚® Chemplate‚®, each student tests seven different salt solutions for relative pH. They predict relative strength, and determine whether the salt hydrolyzed in water to produce an acidic or basic solution. This is all done through observation.
Scientific Concepts:
- Discover why salts vary in neutrality
- Determine relative pH and strength of various salt solutions
- Determine the effect of hydrolysis in producing acids or bases
