Chemistry Quiz on Solutions

What is the definition of a saturated solution?

• A solution with less solute than can be dissolved by the solvent.

• A solution where the solvent does the dissolving.

• A solution with exactly the right amount of dissolved solute for a particular solvent.

• A solution that increases the rate of dissolving when heated.

Which of the following is true about the factors affecting solubility?

• Pressure decreases the solubility of gases in liquids.

• Nonpolar solvents dissolve polar solutes.

• Increasing temperature generally increases the solubility of solids in liquids.

• Agitation decreases the rate of dissolving a solute.

What type of compounds conduct electricity in aqueous solutions or when melted?

• Organic compounds such as alcohols and sugars.

• Nonmetal molecular compounds.

• Electrolytes such as NaCl, KCl, etc.

• Distilled water.

What is the effect of agitation on the rate of dissolving a solute?

• It has little to no effect.

• It decreases the rate of dissolving.

• It increases the rate of dissolving.

• It only affects the solubility of gases.

Which statement best describes a supersaturated solution?

• Contains less dissolved solute than a saturated solution.

• Contains more dissolved solute than can be dissolved by the solvent under normal conditions.

• Contains exactly the right amount of solute that can be dissolved by the solvent.

• Is typically very stable and does not require special conditions.

What does the solute represent in a solution?

• The substance in which the solute is dissolved

• The substance being dissolved

• The temperature at which the solution is prepared

• The solid formed after the solution process

What is indicated by a point on the line of a solubility curve?
