Back

Solute

Front

What is the effect of stirring (agitation) on the rate of dissolution of a solid solute in an aqueous solution?

Back

It increases the rate.

Front

What describes the concentration of a solution?

Back

The amount of solute in a given amount of solvent.

Front

How does agitation affect the rate of dissolution?

Back

Agitation increases the rate of dissolution (dissolves faster).

Front

How does increasing the surface area of a solid solute affect its rate of dissolution?

Back

It increases the rate.

Front

What is a solvent?

Back

A solvent is the substance that dissolves a solute, forming a solution.

Front

What is an aqueous solution?

Back

An aqueous solution is a solution in which water is the solvent.

Front

What is concentration in the context of solutions?

Back

Concentration is the measure of the amount of solute present in a given volume of solvent.

Front

What happens to the solubility of most solids as temperature increases?

Back

The solubility of most solids increases with an increase in temperature.

Front

What is dilution?

Back

Dilution is the process of reducing the concentration of a solute in a solution, usually by adding more solvent.
