- Do precipitation reactions reach a measurable equilibrium?
Yes they do.
- What is a solubility product?
The solubility product, Ksp, is a measure of this equilibrium.
- What is the common ion effect?
When a salt (with an ion in common with a precipitate) is added to a solution of the solid precipitate and a decrease in the solubility of the precipitate is observed.
- Calculate the solubility for the following solutions
- Ag2CO3. (Ksp = 8.1 x 10-12)
1.27 x 10-4 M
- Ag2CO3 in 0.10M AgNO3.
8.1 x 10-10 M
- Ag2CO3 in 0.20M Na2CO3
3.18 x 10-6 M
