3.1.4 Solutions

Question 1

What is a solute?

Answer 1

The substance which is going to be dissolved

Question 2

What is a solvent?

Answer 2

The liquid which is going to be doing the dissolving

Question 3

What is a solution?

Answer 3

The resulting mixture of the solute dissolved in the solvent

Question 4

What doe saturated mean?

Answer 4

A solution in which no more solute can be dissolved

Question 5

What is suspension?

Answer 5

A solid floating in a liquid because it cannot be dissolved

Question 6

What does soluble mean?

Answer 6

A substance that can be dissolved

Question 7

What does insoluble mean?

Answer 7

A substance that cannot be dissolved

Question 8

What is the solute, solvent and solution when dissolving salt into water?

Answer 8

Salt - solute
Water - solvent
Saltwater - solution

Question 9

What unit is solubility measured in?

Answer 9

g per 100g of solvent

Question 10

What is a solubility curve?

Answer 10

A graph that shows how solubility varies with temperature

Question 11

What are the three parts of a solubility curve?

Answer 11

The line - saturated (shows that maximum mass of solid that can be dissolves at each temperature)
Below the line - soluble (less than the maximum solid, so it will all dissolve)
Above the line - insoluble (more than the maximum mass of the solid, so some will dissolve and some won’t. The mass that dissolves can be found by reading off the line)
