Ch.13 Chem

Front 1

solution

Back 1

homogeneous mixture of solutes and solvents

Front 2

solvent

Back 2

greatest quantity - substance that that does the dissolving

Front 3

solute

Back 3

substance that is being dissolved - uniformly dispersed

Front 4

molecular level

Back 4

intermolecular forces b/w solvent and solute must be great enough to compete w/ intermolecular forces w/i solute and solvent independently

Front 5

3 steps of solvation

Back 5

1) seperation of solute molecules, delta H1
2)seperation of solvent molecules, delta H2
3)formation of solvent-solute interactions, delta H3

Front 6

spontaneity

Back 6

process in which the energy of the system decreases, a decrease in energy due to an increase in the disorder or randomness of your system (solution)

Front 7

entropy

Back 7

a thermodynamic measure of the amount of disorder in a system - process which increase entropy tend to occur spontaneously

Front 8

solubility of a solute

Back 8

amount of a solute which will dissolve to form a saturated solution @ a certain temp

Front 9

unsaturated solution

Back 9

solution upto the pt. of saturation

Front 10

factors affecting solubility

Back 10

1)nature of solute
2)nature of solvent
3)temp
4)pressure (gases)
