Solubility Answers

Three students are mixing the same type of solute in 500 ml of water. Jessica is heating her solution, Larry left his on the counter at room temperature, and Hunter is heating his solution while stirring it.

The chart shows the solubility of different substances.

A substance is boiled repeatedly and stirred, but the solute never mixes with the solvent. Which best describes why?

The chart shows the amount of solute that fully dissolved when added to 500 ml of water.

Oil and water placed in a jar will separate. Even when shaken and mixed, the oil still separates from the water.

Four solutes are added to a solvent. All solutes have the same mass and solubility. The surface areas of four solutes are 2 mm2, 4 mm2, 6 mm2, and 10 mm2. Which solute will dissolve the quickest?

Which refers specifically to a heated solution that holds more dissolved solution than it can hold at a lower temperature?

Which refers specifically to a solution with as much dissolved solute as it can hold at a given temperature?

How does temperature affect the speed with which the solute dissolves?

The cell membrane around a cell forms a barrier that protects and regulates the cell. Certain chemicals can pass through the plasma membrane because they have similar chemical properties as the membrane.
