Saturated, Unsaturated & Supersaturated Solutions Solution, in which the concentration of solute is that determined by its solubility (at given temperature) is called SATURATED solution. One cannot add more solute to such a solution. We also say that a saturated solution is in equilibrium with pure solute: If we add solid Nacl to an already saturated solution of NaCl, that solid remains in equilibrium with dissolved Naci. Solution containing less solute than would be in the saturated solution, is UNSATURATED...

solubility curve of salts
Solubility Curve of Salts ( Extra Credit: Maximum of 5 pts.) The solubility curve for solutes describes at what the temperature its solution will be saturated (maximum solubility). Beyond that amount, the salt will start to crystallize. The solubility of sodium chloride and potassium chloride in water at different temperatures is given in the table below: Naci КСІ Temp (C) Solubility (g/100g H2O) Temp (C) Solubility (g/100g H,O) 0 35.65 28 10 35.72 35.89 20 30...
