Solubility Constants and Common Ion Effect

Question 1: The solubility constant is equal to the equilibrium constant.

Question 2: To find the solubility constant, the concentration of individual ions must be considered.

Question 3: What is the concentration of calcium ions in a saturated calcium carbonate solution at 25°C

Question 4: If a precipitate forms in solution when two salt solutions are mixed, what must be true about the K_sp?
