Template by Bill Arcuri, WCSD The process of water molecules pulling away the ions from an ionic compound.

Template by Bill Arcuri, WCSD What is hydration?

The process of breaking up an ionic compound into the separate ions. Template by Bill Arcuri, WCSD

Template by Bill Arcuri, WCSD What is ionization or dissociation

Template by Bill Arcuri, WCSD The difference between a strong and weak electrolyte

Template by Bill Arcuri, WCSD The ions that break apart or not.

Template by Bill Arcuri, WCSD When a solution that can hold all the possible solute possible.

Template by Bill Arcuri, WCSD What is a saturated solution

Template by Bill Arcuri, WCSD Is a weak electrolyte because there are few ions to conduct electricity

Template by Bill Arcuri, WCSD Any weak acid, covalent compound, or insoluble ionic compound

Template by Bill Arcuri, WCSD What is the pH equation

Template by Bill Arcuri, WCSD pH=-log[H 3 O + ]

Template by Bill Arcuri, WCSD What is a stong acid vs. weak acid

Template by Bill Arcuri, WCSD A strong acid has more dissociation than a weak acid.

Template by Bill Arcuri, WCSD What is boiling point elevation

Template by Bill Arcuri, WCSD Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent.

Template by Bill Arcuri, WCSD What is the boiling point elevation equation

Template by Bill Arcuri, WCSD ΔTb = iK b m

Template by Bill Arcuri, WCSD What does ΔTb = iK b m mean

Template by Bill Arcuri, WCSD “i” is number of ions Kb is constant given in back of book m is molality t is temperature

Template by Bill Arcuri, WCSD What is freezing point depression?

Template by Bill Arcuri, WCSD Freezing point depression occurs when the freezing point of a liquid is lowered by adding another compound to it. The solution has a lower freezing point than that of the pure solvent.

Template by Bill Arcuri, WCSD Freezing point depression will do what to waters freezing point

Template by Bill Arcuri, WCSD Make it go below 32 degrees F or 0 degrees C

Template by Bill Arcuri, WCSD What is the freezing point depression equation

Template by Bill Arcuri, WCSD ΔT F = K F · b · i

Template by Bill Arcuri, WCSD What does ΔT F = K F · m · I mean

Template by Bill Arcuri, WCSD “i” is the number of ions K f is a constant T is temperature m is molaity
