Rate of Dissolving Practice

The main substance in a solution that dissolves other substances.

• solute

• solvent

• solution

• solubility

Any substance that gets dissolved in a solution.

• solute

• solvent

• solution

• solubility

A type of mixture where the substances are evenly mixed together.

• solvent

• solute

• solution

• solubility

The amount of a solute in a given amount of a solution.

• Concentration

• Dissolution

• Dilution

• Agitation

When you lower the concentration of a solution by adding more solvent.

• Dilution

• Solubility

• Concentration

• Aqueous Solution

The process of mixing a substance into a liquid so that it is dissolved.

• Concentration

• Dissolution

• Solubility

• Solvent

How fast a substance dissolves in a liquid.

• Rate of Dissolution

• Surface Area

• Aqueous Solution

• Solubility

Why does the rate of dissolving increase as the temperature increases?

• The solute molecules move faster at higher temperatures

• The solute particles become smaller at higher temperatures

• The solvent molecules become slower at higher temperatures

• What is the effect of agitation on the rate of dissolving?

How does agitation help in dissolving a solute more quickly?

• It increases the temperature of the solvent

•  It increases the weight of the solute

• It brings fresh solvent into contact with undissolved solid

• It changes the shape of the solvent

What can increase the rate of dissolving even further?

• Using a solute with a larger particle size

• Using a solute with a smaller particle size

• Decreasing the temperature of the solvent

• Decreasing the agitation of the mixture
