Question 13

what is a solvent

Answer 13

A solvent is a liquid that dissolves something else.

Question 14

example of a solvent

Answer 14

For example, in saltwater, water is the solvent because it dissolves the salt.

Question 15

what is a solute

Answer 15

A solute is a substance that gets mixed into and dissolves in another substance.

the solid that is dissolved by a solvent

Question 16

example of a solute

Answer 16

For example, in salt water, salt is the solute because it dissolves in the water.

Question 17

what is a solution

Answer 17

A solution is a mixture where one substance (like salt) dissolves completely in another substance (like water).

The dissolved particles spread out evenly, and you can’t see them separately.

Question 18

example of a solution

Answer 18

For example, when you stir sugar into water, it becomes a solution.

Question 19

how does a solution form

Answer 19

A solution forms when a solute dissolves in a solvent

Question 20

what is a saturated solution

Answer 20

A saturated solution is one in which no more solute will dissolve (at a given temperature)

the maximum amount of solute that can be dissolved

Question 21

soluble

Answer 21

dissolves well in liquid

Question 22

insoluble

Answer 22

does not dissolve well in liquid

Question 23

what is solubility

Answer 23

Solubility is defined as the mass of a solid required to saturate 100 g of
water at a given temperature.

the mass of solute that can saturate 100 cm3 of solvent

Question 24

solubility formula

Answer 24

Solubility = Volume of Water (L) / Mass of Solute (g)​

Question 25

what does concentrated mean

Answer 25

Concentrated - large amount of solute

Question 26

what does dilute mean

Answer 26

Dilute - small amount of solute
