SQ: Solubility

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent, forming a solution.

Front

What factors affect solubility?

Back

Factors affecting solubility include temperature, pressure, particle size, and stirring.

Front

How does temperature affect solubility?

Back

Generally, increasing temperature increases the solubility of solids in liquids, while the effect on gases can vary.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature and pressure.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature and pressure.

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature and pressure.

Front

How does particle size affect the rate of dissolution?

Back

Smaller particles have a larger surface area, which allows them to dissolve faster than larger particles.

Front

What role does stirring play in solubility?

Back

Stirring increases the interaction between solute and solvent, helping the solute to dissolve faster.

Front

Why do sugar particles dissolve faster in hot water?

Back

Sugar dissolves faster in hot water because the water particles move faster, increasing collisions with sugar particles.

Front

What is the solubility of KClO3 at 0 ºC?

Back

KClO3 is one of the least soluble substances at 0 ºC compared to other salts.
