Solubility Equilibria (I)
Lesson Hook:
A trick question; "Is AgCl2 insouble?"Students will reply that it is insoluble, and their reasoning may lie on the solubility chart/rule that you would have introduced before this lesson.
Lesson:
Inform the students that nothing is really completely "insoluble". All chemicals, to some extent are soluble (in water), the degree of solubility just varies with the compounds. AgCl2 dissolves to some extent, but it is a negligible amount. This is a great time for the solubility equilibria will be introduced to the students. Lead the students through some sample questions that involves the ICE chart. They've been working on this for all these lessons, and should more or less feel comfortable performing calculations with the ICE chart.
Consolidation:
Solubility constants and the molar solubility of some of the soluble and insoluble salts should be provided for the students to analyze and discuss. They will be able to relate Ksp to the molar solubility, which may clear up some understanding in this lesson.
