alex dissolves

1. Alex dissolves 19.8 g solute into 38.0 g water and finds that crystals first appear in the solution at temperature: 11.0 °C, calculate the solubility of the solute. 2. a. A mixture of 42.00 g water and 15.44 g of KNO, looks clear solution at 84 °C. As it cools down to 71°C, a few crystals start to appear. Will it be saturated or unsaturated solution at 62"C? b. A mixture of 30.00 g water and 18.45 g of NH,Cl is made and heated. At 90 °C it is a clear, colorless solution. As it cools, a few crystals appear when it reaches 46 °C At 56°C, what kind of solution is it? 3. if solubility of a salt at 25°C is 58 g/100 & 60 g of the salt is in 120 g water at the same temperature. Describe the nature of the solution (saturated or unsaturated & why).

g of sodium nitrate (NaNO,) dissolves in 100 g of water at 20°C. Is this solution saturated or unsaturated? Wha t would happen if you added ten more grams of sodium nitrate to the solution? What would if you added the ten grams and raised the temperature to 40 C? lution is unsaturated. Adding ten additional grams of solute (NaNO,) would result in a homo geneous solution.

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...
