Brownian Motion
Chaotic movement of colloidal particles
\-caused by collisions of medium particles and colloidal particles
\-caused by collisions of medium particles and colloidal particles
13
New cards
Emulsion
Mixture of 2 insoluble liquids
14
New cards
Solute
Being dissolved
15
New cards
Solvent
Dissolves the solute
16
New cards
Electrolyte
Conducts electricity when dissolved in water
17
New cards
Nonelectrolyte
Dissolves in water, but does not conduct electricity
18
New cards
Strong Electrolytes
Substances that ionize completely
\-Includes all strong acids, strong bases, and soluble ionic compounds
\-Includes all strong acids, strong bases, and soluble ionic compounds
19
New cards
Weak Electrolytes
Ionize only partially
\-Includes weak acids, weak bases, and insoluble ionic compounds
\-Includes weak acids, weak bases, and insoluble ionic compounds
20
New cards
Solvation
Process of attraction and association of molecules of a solvent with molecules or ions of a solute
21
New cards
Dissociation
When molecules split into other things
22
New cards
Spectator Ions
Ions that do not take part in the chemical change
23
New cards
Saturated
Holds maximum amount of solute
\-undissolved solute remains at bottom
\-undissolved solute remains at bottom
24
New cards
Unsaturated
Solvent can still dissolve more
25
New cards
Supersaturated
Holds more than a saturated solution
\-Raise temperature to dissolve more solute, then lower the temperature
\-Solute remains dissolved
\-Solvent is now holding more than it should at a new temperature
\-Raise temperature to dissolve more solute, then lower the temperature
\-Solute remains dissolved
\-Solvent is now holding more than it should at a new temperature
26
New cards
Miscible
2 or more liquids dissolve in each other
27
New cards
Immiscible
2 or more liquids will not dissolve in each other
28
New cards
Temperature and Solubility
\-Solid solubility increases
\-Gas solubility decreases
\-Gas solubility decreases
29
New cards
Pressure and Solubility
\-Little effect on solubility of solids and liquids
\-Strong influence on the solubility of gases
\-Increased pressure=increased solubility
\-Strong influence on the solubility of gases
\-Increased pressure=increased solubility
30
New cards
Henry’s Law
Solubility of a gas is directly proportional to the pressure
