A supersaturated solution is best described as a solution that -

• reaches a higher temperature than is normally possible.

• is made up of more ions than any other solution.

• contains more solute than is normally possible.

• can dissolve more substances than any other solution.

The graph below illustrates the solubility of potassium chloride in water at a variety of temperatures. At what temperature does 30 g of KCl dissolved in 100 g of water create a saturated solution?

• 10° C

• 20° C

• 30° C

• 40° C

Increasing temperature affects solubility because, at warmer temperatures, water-

• has slower-moving particles.

• dissolves a larger amount of solute.

• dissolves a smaller amount of solute.

• has slower-moving particles.
