1

_____: what is dissolved

solute

2

______: what does the dissolving
ex: salt water is a solution

solvent

3

_______: solute will dissolve : salt/sugar are ... in water

miscible

4

____: solute will not dissolve: oil & water are ...

immiscible

5

oil (_______) + water (______) = immiscible

non-polar oil
polar water

6

salt (or sugar) and water are both polar so it is ______

miscible

7

Grease gets ripped up when you scrub the pan with soap.
______: breaking large droplets of grease into small droplets

emulsification

8

how do you increase the rate of dissolving?

1.) stir solute and solvent
2.) increase surface area of solute (crush / grind into powder).
3.)heat up solvent (heat = motion) so molecules move faster - more contact.

9

Non-polar (___) + polar (____) = immiscible

Oil
Water

10

What does emulsification mean?

Emulsification is breaking large droplets of grease into small droplets

11

How do you increase the rate of dissolving?

1.) stir solute and solvent
2.) increase surface area of solute (crush / grind into powder)
3.)heat up solvent (heat = motion) so molecules move faster - more contact.

12

________: 15 gallons of H2O in air (humidity)
_____ is polar

Condensation
water

13

What do molecules do in a warm room?

molecules move too quickly to stick in a warm room.

14

What do molecules do on cold windows?

Molecules slow down and stick

15

Will molecules stick in a warm room?

NO! Molecules move too quickly to stick in a warm room.

16

What do molecules do on a cold window?

The molecules will SLOW DOWN and STICK
- causes CONDENSATION

17

COLD WINDOWS--> The molecules will SLOW DOWN and STICK. This causes ________

condensation

18

What is the maximum amount of humidity?

4%

19

_________:more solute can be dissolved / added

unsaturated ; 1 tsp sugar

20

____: no more solute will dissolve

saturated; 4 tsp sugar

21

Why won't crystal dissolve?

saturated

22

____________
1.) saturated solution at warm temperature
2.) seal container
3.) cool down

Super Saturated Solution

23

what is SUPER SATURATED SOLUTION?

1.) saturated solution at warm temperature
2.) seal container
3.) cool down
