solutions

Question 1

The particles in a colloid remain dispersed throughout the mixture because they _____

Answer 1

are extremely small

Question 2

Distillation can be used to separate solutions of miscible liquids because

Answer 2

different liquids usually have different boiling points

Question 3

What happens when a supersaturated solution cools down

Answer 3

the solute will crystallize out of the solution

Question 4

What happens when the pressure on a soda is decreased?

Question 5

The solubility of a solute depends on

Answer 5

the nature of the solute and the temperature of the solvent

Question 6

a dissolved solute that does no dissolve ions is

Answer 6

a nonelectrolyte

Question 7

Gases are ___ soluble in warm water than in cold water

Answer 7

less (they are soluble in low temp, high pressure)

Question 8

Adding sugar to water ___ the boiling point of the water.

Answer 8

increases

Question 9

unsaturated

Answer 9

capable of dissolving more solute

Question 10

saturated

Answer 10

reached its maximum capacity of solute, additional solute results in undissolved particles,

Question 11

colligative properties

Answer 11

properties that depend on the amount of solute dissolved in the solution

Question 12

What does more dissolved particles mean?

Answer 12

higher boiling point, lower freezing point

Question 13

henry’s law

Answer 13

at a given temperature, the solubility of a gas is directly proportional to the pressure of the gas above the liquid

Question 14

Why is boiling point elevation a colligative property?

Answer 14

It is directly proportional to the concentration of particles in a solution
