Front

What is the universal solvent?

Back

Water is known as the universal solvent because it can dissolve more substances than any other liquid.

Front

What does 'like dissolves like' mean?

Back

It means that polar solvents dissolve polar solutes, and non-polar solvents dissolve non-polar solutes.

Front

What is concentration in a solution?

Back

Concentration refers to the amount of solute that is dissolved in a given amount of solvent.

Front

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

Back

Stirring the solution, crushing the solute, and raising the temperature of the solvent increase the rate of dissolving.

Front

Is potassium hydroxide (KOH) soluble or insoluble?

Back

Potassium hydroxide (KOH) is soluble in water.

Front

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

Define solvent.

Back

A solvent is a substance that dissolves a solute, resulting in a solution.

Front

What is a saturated solution?

Back

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

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more dissolved solute than a saturated solution at the same temperature.

Front

What is the effect of temperature on solubility?

Back

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