as temperature of a solid increases, solubility ________

increases

as temperature of a gas increases, solubility _________

decreases

what is a solution

a homogenous mixture of two or more substances

two ways to increase the rate of solution for a solid being dissolved in a liquid

increase temp, stir

for an exothermic reaction, list two things that cause a shift to the left

decrease pressure, decrease concentration

if concentration of a reactant increases, the reaction will shift which way?

right

if concentration of a product increases, the reaction will shift which way?

left

compound

cannot be physically separated

solution

can be separated

how do you separate a solution

fractional distillation

define a solution:

a homogenous mixture of two or more solutions

molarity

mol/volume

molality

mol/kg; unit mol/kg

molarity

mol/L; M

hydration

each cation is surrounded by the negative ends of the water molecules and each anion is surrounded by the positive ends. the water molecules literally keep the ions apart; once the water evaporates, the ions recombine and salt crystals reform

osmosis

movement of particles across a semi-permeable membrane

solvation

Solvation is the process in which molecules of a solvent surround and interact with solute particles, breaking them apart and dispersing them throughout the solvent.

lachateliers principle

when a system at equilibrium is disturbed , the equilibrium position shift
