30 Cards in this Set

  • Front
  • Back
hydroscopic
salts taht absorb water from the air
efflorescence
to lose water of hydration
deliquescent
describes a substance that removes sufficient water from the air to form a solution
example of something deliquescent
CaCl2
water of hydration
water molecules that are an integral part of a crystal struction
example of water of hydration structure
CuSO4 . 5H20
desicant
a hydroscopic substance used as a drying agent
anhydrous
a salt that has lost its water of hydration
serial dilutions
1 M, .1M, .01M, .001M,
solutions
homogenous
suspension
heterogenous mixture from which the particles settle out upon standing; the particle size is usualy greater than 100 nanometers
colloid
heterogenous mixture where the particles are smaller than a suspension but bigger than a solution
example of colloids
milk, mayonaise, fog, jelly, paint, helatain,
5 types of solutions
1. weak
2. strong
3. saturated
4. unsaturated
5. supersaturated
weak solution
dilute- not much solute
strong solution
concentrated
saturated solution
holding all the solute that the solvent can
unsaturated
holding less solute than the solvent can
supersaturated
holding more solute than is normally possible
two supersaturated solutions
1. NA acetate
2. NA thiosulfate
temp of a fas and solubility
as the temp of a GAs increase, the solubility decreases
factors affecting solubility
nature of the solvent/solute
temp
polarity
pressure
factors affecting the rate of solubility
agitation/stirring
temp (higher=faster)
pressure
temp and vapor pressure
higher temp=higher vapor pressure
formula for molaRity
molarity= number of moles
----------------
L of solution
formula for molaLity
molality= number of moles
---------------
i kG solvent
difference between molaRity and molaLity
molarity= affected by temp and press
molality= not affected by temp and press
one molal
one molal= 1 mole
-------
1000 kg solvent
colligative properties
properties of a solution that depend on the number of solute particles, not the type of particles
-the more particles in the solution, the more change in the properties
examples of colligative properties
freezing point, boiling point, vapor pressure
