rate of dissolution

Front

What is the rate of dissolution?

Back

The rate of dissolution is the speed at which a solute dissolves in a solvent to form a solution.

Front

What factors can affect the rate of dissolution?

Back

Factors include temperature, surface area of the solute, agitation (stirring), and the nature of the solute and solvent.

Front

How does temperature affect the rate of dissolution?

Back

Increasing the temperature generally increases the rate of dissolution because particles move faster and collide more often.

Front

What is a solute?

Back

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

Front

What is a solvent?

Back

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

Front

What is a solution?

Back

A solution is a homogeneous mixture of two or more substances, where the solute is evenly distributed within the solvent.

Front

How does particle size affect the rate of dissolution?

Back

Smaller particles have a larger surface area, which increases the rate of dissolution compared to larger particles.

Front

What happens to the rate of dissolution when you stir a mixture?

Back

Stirring increases the rate of dissolution by distributing the solute particles throughout the solvent more quickly.

Front

What is the effect of cold water on the rate of dissolution?

Back

Cold water slows down the rate of dissolution because the particles move more slowly.

Front

True or False: The finer the particles, the slower the rate of dissolving.

Back

False. Finer particles dissolve faster due to increased surface area.
