You have prepared a saturated solution of X at 20∘C using 27.0 g of water. How much more solute can be dissolved if the temperature is increased to 30∘C?
Express your answer with the appropriate units.
Homework Answers
Grams of water used for the saturated solution is 27.0 g. Now at 20 oC, the solubility of X is 11.0 g in 100 g of water., thus the amount of solute present in the 27.0 g water solution = 11*27/100 g = 2.97 g.
Now, if the temperature has raised to 30 oC, then the saturated solution will contain = 23*27/100 g = 6.21 g of solute in the solution at this temperature.
Thus the extra amount of solute that can be dissolved = (6.21-2.97) g = 3.24 g.

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...
