Types of Solutions

Question 1

Solution

Answer 1

a homogeneous mixture of two or more substances
 - uniform throughout
- can have different compositions unlike pure substances such as different ratios of solute to solvent

Question 2

solvent

Answer 2

is any substance that has another substance 
dissolved in it. (usually in the largest amount)

Question 3

solute

Answer 3

is a substance dissolved in the solvent.

Question 4

aqueous solutions

Answer 4

water is the solvent

Question 5

Miscible liquids

Answer 5

can be combined in any proportion, they are 
readily dissolvable. i.e. Any amount of water dissolves in any 
amount of ethanol and any amount of ethanol dissolves in any 
amount of water. Anything miscible must always be LIQUID!

Question 6

immiscible liquids

Answer 6

liquids that do not dissolve easily

Question 7

saturated solutions

Answer 7

formed when no more solute can dissolve

Question 8

unsaturated solutions

Answer 8

more solute can dissolve

Question 9

supersaturated solution

Answer 9

solution that contains more dissolved solute than a saturated solution at the same temperature. A change in temperature can cause a saturated solution to become supersaturated. solids dissolved in water become supersaturated when cooled. most solutions of a gas in liquid become supersaturated when heated.

Question 10

why are supersaturated solutions unstable?

Answer 10

• Because the solute in a supersaturated solution is present in a concentration higher than the equilibrium concentration
• if a crystal of a solute is added to a supersaturated liquid solution of the solute, the excess solute will precipitate, leaving the solution saturated. also, a disturbance in a supersaturated solution of a vapour in air can cause the vapour to condense into droplets.

Question 11

sparingly soluble

Answer 11

when the solubility is between 0.1g and 1g in 100ml of solvent.

Question 12

insoluble

Answer 12

less than 0.1 gram of solute will dissolve per 100 ml of solvent (usually water)

Question 13

water properties

Answer 13

is polar so it can dissolve ions (ionization)

Question 14

colloids

Answer 14

compounds suspended in things are not solutions since the solvent has not been able to dissolve the compound.

Question 15

insoluble compound… saturated?

Answer 15

an insoluble compound can be saturated because it will be all the solute it can take

Question 16

Supersaturated solids in liquid

Answer 16

• saturated solutions of a solid dissolved in water become supersaturated when cooled.

Question 17

supersaturated gas in a liquid

Answer 17

Increasing the temperature for a solution that contains dissolved gas molecules provides energy for the gas molecules to escape. This is why the solubility decreases when you heat the solution

Question 18

aqueous solution

Answer 18

solution with water

Question 19

solid solid:

Answer 19

steel

Question 20

solid liquid:

Answer 20

seawater

Question 21

solid dissolved in gas:

Answer 21

gases that separate from a mothball

Question 22

• liquid in solid

Answer 22

liquids dissolved in wax that make it easier to apply

Question 23

• liquid in liquid:

Answer 23

antifreeze for cars

Question 24

• liquid in gas:

Answer 24

humidity results from water dissolving in air

Question 25

• gas in solid:

Answer 25

ice has dissolved air

Question 26

• gas in liquid

Answer 26

pop

Question 27

• gas in gas

Answer 27

air!
