17
Q

ways to dissolve

A

crushing the solute
stirring
heating the solvent

18
Q

what is solute?

A

what gets dissolved

19
Q

what is solvent?

A

what does the dissolving

20
Q

what is solution equilibrium?

A

dissolution and crystallization occur at the same rate

21
Q

what is saturated?

A

the maximum amount of solute

22
Q

what is unsaturated?

A

less than the maximum amount of solute

23
Q

what is supersaturated?

A

more than the maximum amount of solute

24
Q

what is solubility?

A

amount of solute needed to make a saturated solution

25
Q

like dissolves like

A

polar dissolves polar
nonpolar dissolves nonpolar
polar dissolves ionic

26
Q

what is immiscible?

A

2 liquids that don’t mix

27
Q

henry’s law

A

dissolving gas into liquid, you add pressure using the same gas

28
Q

example of henry’s law

A

carbonation in soda

29
Q

effects of temperature on solubility

A

temperature helps solid dissolve into liquid but doesn’t help gas dissolve to liquid

30
Q

what is solvated?

A

when solute is surrounded by solvent

31
Q

what is enthalpy of solution?

A

energy released or absorbed when solution is made

32
Q

step 1 of energy changes

A

energy absorbed

solute particles are removed from solids

33
Q

step 2 of energy changes

A

energy absorbed

solvent molecules get moved from solid

34
Q

step 3 of energy changes

A

energy released

solvent surrounds solute

35
Q

what is concentration?

A

amount of solute in a given amount of solution

36
Q

what is molarity?

A

moles of solute / liters of solute

37
Q

M =

A

mol / L

38
Q

mol =

A

ML

39
Q

L =

A

mol / M

40
Q

what is molality?

A

moles of solute / kg of solvent
