This question has multiple parts. Work all the parts to get the most points. a Potassium sulfate has a solubility of 15 g/100 g water at 40°C. A solution is prepared by adding 47 g of potassium sulfate to 175 g of water, carefully heating the solution, and cooling it to 40°C. A homogeneous solution is obtained. Answer the following questions to determine whether the solution is saturated, unsaturated, or supersaturated. How many grams of potassium sulfate would dissolve in...

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...
