What is a concentrated solution?

Back

A concentrated solution is one that has a large amount of solute dissolved in a given amount of solvent, resulting in a dark color and strong flavor, such as a very sweet Koolaid mix.

Front

How can a solution become supersaturated?

Back

A solution becomes supersaturated by dissolving more solute than the solvent can normally hold at a given temperature, often achieved by heating the solution and then cooling it.

Front

Which salt is least soluble at 40°C?

Back

KClO3 (Potassium Chlorate) is the least soluble salt at 40°C.

Front

What is a solute?

Back

A solute is a substance that is dissolved in another substance, typically in a solution.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one in which less solute is dissolved than the solvent can hold at a given temperature, meaning more solute can still be added.

Front

What is a solvent?

Back

A solvent is the substance in which the solute is dissolved to form a solution, usually present in a greater amount.

Front

What is the difference between a saturated and an unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can be dissolved at a given temperature, while an unsaturated solution contains less solute than the solvent can hold.

Front

What factors affect the solubility of a substance?

Back

Factors that affect solubility include temperature, pressure (for gases), and the nature of the solute and solvent (polarity, molecular size, etc.).

Front

What is a supersaturated solution?

Back

A supersaturated solution is one that contains more solute than can normally be dissolved at a given temperature, often achieved through specific methods.

Front

What is the role of temperature in solubility?

Back

Temperature generally increases the solubility of solids in liquids, while it can decrease the solubility of gases in liquids.
