Solutions And Their Behavior Flashcards
Solution:
A homogenous mixture that consisted of one or more solutes in a medium (solvent)
(Molarity)
Solvent:
Is present in the larger amount
Molality
Solute:
Is present in the smaller amount than the solvent
Is molality ever equal to molarity?
No
_______ is better when dealing with solution stoichiometry
Molarity
_______ is better when dealing with physical chemistry
Molality
Solubility:
The amount of solute that will dissolve in a given amount of solvent.
Saturation:
A solution that contains the maximum amount of a solute, as defined by its solubility.
Supersaturated:
A solution contains more solute than allowed by the solubility.
Miscible
Two liquids are miscible if they are soluble in each other in all proportions.
Polar solutes are more or less soluble in polar solvents?
More
Nonpolar solutes are more or less soluble in nonpolar solvents?
More
Lattice energy is…
Energy released when molecules or ions settle into a crystalline lattice. (Exothermic)
Solvation (hydration) energy is…
Energy released when an ion (or molecules) settles into a sphere of solvent molecules (Exothermic)
As gas pressure >…
Solubility >
Henry’s Law. S=kP (k constant)
Henry’s Law
The amount of non reacting gas which dissolves in liquid in proportional to the PP of the gas. Temp is constant.
As Liquid and solid Temperatures >,_____ _______.
Solubility >.
Temperature effect
The amount of gas dissolved in inversely proportional to temperature. The colder the liquid, the more gas that will dissolve in the liquid.
The vapor pressure of a solution is given by ____________ Law.
Raoult’s
As vapor pressure goes down…
Boiling point goes up.
Osmosis
Diffusion of water through a semipermeable membrane.
A hypertonic spinal solution will go down the spinal column because…
It is heavier. (A hypotonic solution will go up)
As GAS Temperature >, _____ __.
Solubility decreases.
