Factors Affecting Dissolving Rates

Front

What is the main factor that increases the rate of dissolving a solute in a solvent?

Back

Agitation, which brings fresh solvent into contact with undissolved solid.

Front

How does particle size affect the rate of dissolving?

Back

Using a solute with a smaller particle size increases the rate of dissolving.

Front

What is an aqueous solution?

Back

A solution where water is the main liquid.

Front

How can warming a solute affect its dissolving rate?

Back

Warming the solute can speed up the rate of dissolving.

Front

What happens to the rate of dissolution when the surface area of a solute is increased?

Back

The rate increases.

Front

What is the effect of temperature on the rate of dissolving?

Back

Generally, increasing the temperature of the solvent increases the rate of dissolving.

Front

What is the definition of dissolution?

Back

The process of a solute dissolving in a solvent to form a solution.

Front

How does the concentration of a solute affect its dissolving rate?

Back

Higher concentrations can slow down the rate of dissolving due to saturation.

Front

What is the relationship between solute temperature and solubility?

Back

In many cases, higher temperatures increase solubility.
