Question 1 of 3

1. Question
The common ion effect tells us that the solubility of a slightly soluble salt will
- increase when adding more of the anion of the salt.
- increase when adding more of the cation of the salt.
- decrease when adding more of the anion of the salt.
- always remain constant.
- double when adding sodium chloride to the solution.
