Answer to Question #170808 in Inorganic Chemistry for Jones M Kerkula

Question

What was added to 50.0g of NaCl to produce 100cm3 of a saturated solution at 25C?

Answer 1

A saturated solution is a solution in which the concentration of the solute is equal to that concentration that would be in equilibrium with undissolved solute.

Individual Na+ and Cl− ions may transition back and forth between the dissolved state and the solid state. Use the salt shaker to add salt to the point where you see some of the Na and Cl ions remain bonded together. As time goes by, you will see some of the ions leave the salt crystal (solid NaCl) while other ions that were free in solution will bond onto the crystal.
