Bronsted-Lowry Acid: a proton donor
Bronsted-Lowry Base: a proton acceptor
Oxidation-reduction reaction (redox): a reaction in which there is a net movement of electrons from one reactant to or towards another
oxidation number: the charge an atom has or would have if all unevenly shared electrons were transferred completely
on: elemental form: 0
on: monatomic ion: on = ionic charge
on: sum of on in compound: equals zero
on: (1): 1
on: (2): 2
on: hydrogen: +1 when in combination with nonmetals
on: fluorine: -1 in combination with metals and boron
on: oxygen: -1 in peroxides, -2 in other compounds, except with F
on: (17): -1 with metals, nonmetals (besides O), and halogens lower in the group
on: S8: 0
on: Al2O3: Al = +3 O= -2
on: N2H4: N = -2 H = +1
on: S2(O3)2-: S = +2 O = -2
on: HP(O4) 2-: H = +1 P= +5 O = -2
on: CH3OH: C = -2 H = +1 O = -2
if x loses electrons⬦..: x is oxidized x is the reducing agent x increases its oxidation number
if y gains electrons⬦.: y is reduced y is the oxidizing agent y degreases its oxidation number
12.19 mL of 0.1038 M KMnO4 were required to oxidize 25.00 mL of FeCl2. What is the molarity of the FeCl2, given the reaction: MnO4- (aq) + 5 Fe2+ (aq) + 8H+ (aq) ---> Mn2+ (aq) + 5Fe3+ (aq) + 4H2O (l): 0.01276 M
A + B ---> C: Combination
C ---> A + B: Decomposition
A + BC ---> AC + B: displacement
metal activity series: Li, K, Ba, Ca, Na, Mg, Al, Mn, Zn, Cr, Fe, Cd, Co, Ni, Sn, Pb
reversible reaction: reaction that proceeds simultaneously in both directions
equilibrium: the forward reaction and the reverse reaction proceed at equal rates
To standardize an HCl solution, 50.00 mL of HCl is put in flask with indicator. 0.1524 M NaOH goes into buret with initial reading of 0.55 mL and an end point reading of 33.87 mL. What is the concentration of the HCl solution?: 0.1016 M HCl
Oxidation: the LOSS of electrons (LEO)
Reduction: the GAIN of electrons (GER)
