Solubility, Ksp

A precipitate of silver chloride is dissolved upon addition of a clear liquid. Adding a second clear liquid gives a second precipitate. Lastly a third clear liquid is added, dissolving the precipitate again.

 

This reaction demonstrates the difference of solubility of copper chloride in water, and then with addition of sodium hydroxide.

 

Various clear solutions are mixed to form precipitates.

 

 

Demonstration of how to clean up insoluble metal hydroxides in a solution with addition of acid. The copper hydroxide solution made in demo 4.2 or the iron hydroxide solution made in demo 4.4 can be used for this reaction. Milk of Magnesia is used in the second reaction.
