ArrheniusElectrolyte A substance which, when
added to water, causes it to conduct
electricity.Non-electrolyte A substance which
does not cause water to conduct
electricity.Acid A substance which produces
H when added to waterBase A substance which
produces OH- when added to waterWeak acid an
acid which only slightly dissociates in
waterStrong acid an acid which completely
dissociates in waterstrong electrolyte weak
electrolyte non-electrolyteionic cmpds weak
acids covalent cmpdsstrong acids some weak
bases (NH3)

Rules for Oxidation Numbers1. Pure elements
have oxidation 02. O always has oxidation
-2 (except O2)3. H always has oxidation
1 (except H2)4. Dont forget what you
already know (Na 1 F 1 etc)5. The sum of
all valences the charge of the ion
3
Balancing Redox Equations (the oxidation
method)1. From oxidation s determine the
number of electrons gained or lost by the
reactants.2. Cross-multiply the of electrons
(2x5 5x2)to figure the number of these species
in the balanced equation.3. Balance oxygen on
both sides using water molecules.4. Balance
hydrogen on both sides using H ions5. If in
basic solution, cancel H with OH-
