What is the primary reason for the formation of a precipitate in a saturated solution?
Step 1: Understand what a saturated solution is. A saturated solution is one where no more solute can dissolve in the solvent at a given temperature.
Step 2: Know what a precipitate is. A precipitate is a solid that forms and separates from a solution.
Step 3: Learn about ionic products. The ionic product is the concentration of the ions in the solution multiplied together.
Step 4: Understand the solubility product (Ksp). Ksp is a constant that represents the maximum product of the concentrations of the ions in a saturated solution of a salt.
Step 5: Compare the ionic product to the Ksp. If the ionic product (the concentration of ions) is greater than the Ksp, the solution cannot hold all the ions in solution.
Step 6: Conclude that when the ionic product exceeds the Ksp, the excess ions will come together to form a solid, which is the precipitate.
