Preparing Solutions

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

The substance being dissolved is called the ________

• solvent

• solid

• solute

• solvate

When no more solute dissolves the solution is _________

• supersaturated

• unsaturated

• saturated

• supercalifragilisticexpialidocious

What is a substance that is dissolved in another substance? 

• solution

• solute

• solvent

• compound

Kool-Aid - Powder, sugar, and water
Identify the solvent 

• water

• powder

• sugar

• powder and sugar

When a certain amount of solvent cannot hold any more solute it is called a ________ solution.

• Diluted

• Saturated

How does a solution become supersaturated?

• dissolve lots of solute in it.

• dissolve a little solute in it. 

• dissolve more solute than you should be able to. 

• dissolve a solvent in it. 

A mixture with more solute dissolved in the solvent than is usually soluble is called:

• concentrated

• supersaturated

• saturated

• unsaturated

What does it mean to dilute a solution?

• lower the concentration of solute per solvent

• increase the concentration of solute per solvent

Which of the following would dissolve the slowest?

• a sugar cube in hot water

• a sugar cube in cool water

• powdered sugar in cool water

• powdered sugar in hot water
