Question 2

What is a solute

Answer 2

A substance present in a solution in a smaller amount

Question 3

In a solution, the______is dissolved by the _______

Answer 3

Solute, solvent

Question 4

Why is water called the universal solvent

Answer 4

Because it dissolves so many substances

Question 5

What are some facts about the effects of solutes on solutions

Answer 5

Solute a raise the boiling point of a solvent, the temperature must drop lower than 0 degrees celsius for water to freeze when a solute is dissolved in the water, and antifreeze boils at a lower temperature than pure water

Question 6

What is a dilute solution

Answer 6

Mixture that has only a little solute dissolved in a certain amount of solvent

Question 7

Answer 7

Has a lot of dissolved solute in the solvent what is solubility

Question 8

What is solubility

Answer 8

Measure of how much solute can dissolve in a solvent at a given temperature

Question 9

What is a saturated solution

Answer 9

It is when you’ve added so much solute that no more dissolves

Question 10

What is a supersaturated solution

Answer 10

Has more dissolved than is predicted by its solubility at the given temperature

Question 11

What is an unsaturated solution

Answer 11

A mixture in which more solute can be dissolved

Question 12

What are three factors that affect the solubility of a substance

Answer 12

Pressure, type of solvent, and temperature

Question 13

The higher the pressure of the gas, the_____gas can dissolve in a solvent

Answer 13

More

Question 14

What are some facts about temperature and solubility

Answer 14

Most solids become more soluble as the temperature goes up, most gasses become less soluble as the temperature goes up, carbon dioxide dissolves better in cold water than in hot water
