Solutions CP

A student is preparing solutions for a laboratory experiment by dissolving solid solutes in liquid solvents. Which action will increase the rate of solubility

• lowering the temperature of the solvent

• stirring the solute in the solution

• increasing the pressure on the solution

• increasing the particle size of the solute

Which of the following types of solutions has more room to dissolve solute?

• supersaturated

• saturated

• unsaturated

What is a solvent?

• The substance that does the dissolving in a solution.
• The substance that is being dissolved in a solution.
• The mixing of different substances.
• The process in which neutral molecules lose or gain electrons

The concentration of a mixture can be increased in which of the following ways?

• Heating the mixture
• Adding more water “solvent”
• Adding more powder “solute”
• Stirring the mixture

How does temperature generally affect the solubility of solids in liquids?

• Solubility decreases as temperature increases.

• Solubility does not change with temperature.

• Solubility increases as temperature increases.

• Solubility first increases then decreases with an increase in temperature.

Which of the following factors does NOT affect solubility?

• Temperature

• Pressure

• Amount of solute already dissolved

• Color of the solute

Something that cannot be dissolved into a solution is called

• soluble
• insoluble
• solution
• suspension

Which factor does NOT affect the solubility of a substance?

• Temperature

• Stirring

• Color

• Surface Area

What is the effect of surface area on the solubility of a solute?

• Increasing surface area decreases solubility

• Increasing surface area has no effect on solubility

• Increasing surface area increases solubility

• Initially increases solubility, then decreases
