Question 1

Definition of a SOLUTE:

Answer 1

. The substance which is going to be dissolved

Question 2

Definition of a SOLVENT:

Answer 2

. The liquid which is going to do the dissolving

Question 3

Definition of a SOLUTION:

Answer 3

. The resulting mixture if a solute dissolved in solvent

Question 4

Definition of SATURATED:

Answer 4

. A solution in which no more solute can be dissolved

Question 5

Definition of SUSPENSION:

Answer 5

. A solid floating in a liquid because it can’t dissolve

Question 6

Definition of SOLUBLE:

Answer 6

. A substance which can be dissolved

Question 7

Definition of INSOLUBLE:

Answer 7

Question 8

What is the SOLUTE when adding salt to water !?

Answer 8

. Salt

Question 9

What is the SOLVENT when adding salt to water !?

Answer 9

. Water

Question 10

What is the SOLUTION when adding salt to water !?

Answer 10

. Saltwater

Question 11

How do we measure solubility!?

Answer 11

. We measure solubility in
g per 100g of solvent

Question 12

Does solubility vary with temperature !?

Answer 12

. Yes

Question 13

What does THE LINE of a solubility curve suggest !?

Answer 13

. The line = saturated

• shows the Maximum mass of solid which can be dissolved at each temperature

Question 14

What does the area BELOW the solubility curve suggest !?

Answer 14

. Below = Soluble

• less than the maximum mass of solid , so it will all dissolve

Question 15

What does the area ABOVE the solubility curve suggest !?

Answer 15

. Above = insoluble

• more than the maximum mass of solid, some will dissolve and some won’t. (the mass that dissolves can be found by reading off the line)
