Solutions Review

Front

What is a solution?

Back

A homogeneous mixture of two or more substances where one substance (the solute) is dissolved in another (the solvent).

Front

What does 'unsaturated solution' mean?

Back

A solution that contains less solute than it has the capacity to dissolve at a given temperature.

Front

What does 'saturated solution' mean?

Back

A solution that contains the maximum amount of solute that can be dissolved at a given temperature.

Front

What does 'supersaturated solution' mean?

Back

A solution that contains more solute than it can theoretically hold at a given temperature, often achieved by heating.

Front

What is the principle of 'like dissolves like'?

Back

Polar solvents dissolve polar solutes, and non-polar solvents dissolve non-polar solutes.

Front

What factors affect the rate of dissolving a solid in a liquid?

Back

Temperature, surface area of the solid, stirring, and the nature of the solute and solvent.

Front

What is adhesion in the context of solutions?

Back

The attraction between water molecules and other substances, allowing water to stick to surfaces.

Front

What is cohesion in the context of solutions?

Back

The attraction between water molecules to each other, which contributes to surface tension.

Front

What are hydrogen bonds?

Back

Weak attractions between the negative oxygen atom of one water molecule and the positive hydrogen atom of another.

Front

What is the effect of temperature on solubility?

Back

Generally, increasing temperature increases the solubility of solids in liquids.
