AP Chem - we determined how to calculate the molar solubility of a single salt in aqueous solution, and then we quantitatively determined the molar solubility of the same salt in a aqueous solution of a salt that contains a cation or anion in common with the given salt.
We saw that, kinetically, the presence of the common ion causes a greater rate of precipitation than of dissolving, thus, the molar solubility of the given salt is lower/depressed in a solution of its common ion.

Bio - took the unit exam on Sexual Reproduction.
