New cards
Tyndall Effect
The scattering of light by tiny suspended particles
7
New cards
Concentration
How much solute is in the solvent
8
New cards
Dilute
very little solute in the solvent
9
New cards
Concentrated
a lot of solute is dissolved in the solvent
10
New cards
Saturated
the maximum amount of solute is dissolved in the solvent
11
New cards
Unsaturated
less than the maximum amount of solute is dissolved in the solvent
12
New cards
Supersaturated
solution contains more than the maximum amount of solute
13
New cards
Miscible
two or more substances perfectly mix to form a homogeneous mixture
14
New cards
Immiscible
two or more substances are unable to mix and form a homogeneous mixture
15
New cards
Alloy
A mixture containing one or more metals
16
New cards
Electrolyte
Substances that produce ions when dissolved in water
17
New cards
Solubility
how much solute can dissolve in a specific amount of solvent at a specific temp
18
New cards
Dissolution
the act of or process of dissolving
19
New cards
Hydrated ion
When an ionic solute is dissolved in H2O
20
New cards
Henry’s Law
Says when pressure increases more gas will dissolve
21
New cards
Molality
moles solutes per kg solvent
m = mol solute/ kg solvent
m = mol solute/ kg solvent
22
New cards
Precipitate
A solid that forms in a solution during a reaction
\-Insoluble (doesn’t dissolve)
\-Insoluble (doesn’t dissolve)
23
New cards
Colligative Properties
Properties depending on the number of solute particles
\-Physical changes that result from adding a solute
\-Doesn’t change depending on type of solute
\-Physical changes that result from adding a solute
\-Doesn’t change depending on type of solute
24
New cards
Molarity
number of moles of solute per liter of solution
M = mol solute/ L solution
M = mol solute/ L solution
