The sugar cubes are called the

• solute

• solvent

The water is called the

• solvent

• solute

Ernesto and Amanda fill two cups with water. They use hot water in one cup and cold water in the other cup. Next, they will stir a spoon of salt into each cup.     

In which cup will the salt dissolve more slowly? 

• The salt will not dissolve in either cup
• The salt dissolves more slowly in the hot water
• The salt dissolves more slowly in the cold water
• The salt dissolves at the same speed in both cups

• concentration

• saturated solution

• supersaturated mixture

You can make a solution more concentrated by adding __________.

• solute
• solvent
• water

What does it mean to dilute a solution?

• lower the concentration of solute per solvent
• increase the concentration of solute per solvent

__________ are made up of solutes and solvents.

• Solutions

When a solution is saturated:
