Solution Concentration

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

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

Which solution is more concentrated?

• Not enough information to tell

• Solution 1

• Solution 2

• They are equally concentrated

Both of these solutions have a volume of 30 mL. Which solution is more concentrated?

• orange solution

• green solution

• they are equally concentrated

Both solutions have equal volumes of 30 mL. Which solution is more diluted?

• Solution X

• Solution Y

The amount of solute actually dissolved in a given amount of solvent.

• dilution

• concentration

• saturated solution

• supersaturated mixture

In order to dilute a solution, you need to

• add more of the solid

• add more water

• find the mass

• find the volume

The EASIEST way to determine which Koolaid solution is the most concentrated is to...

• compare their mass

• compare their color

• evaporate each solution
