Saturated and Unsaturated Solutions

Dissolving l l l How does something dissolve to make a solution? Dissolving Animation Activity: Measure out 20 m. L of water and 5 g of sugar. Dissolve. Add 5 more grams and continue until saturated. Keep track of the total amount of sugar to calculate the final concentration in g/L.

How much can be dissolved? l l Do you think there is a limit to how much can be dissolved in a solvent? Can you make it more and more concentrated?

Unsaturated Solution l l More solute could dissolve at the same temperature. More solvent particles are available to dissolve solute.

No more solute will dissolve at a specific temperature. All of the solvent particles are already attracted to as many solute particles as they can be. Saturated Solution

Has been heated to dissolve the maximum amount of solute and cooled without stirring. When a single crystal is added to the solution, it grows until the whole solution becomes a solid. Super. Saturated Solution
