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
