Transcript of Drill: Calculate the solubility of PbSO 4 K sp = 2.0 x 10 -14
Chemical Charge• A positive, neutral, or
negative number assigned to a particle & determined by
the difference between the # of protons & electrons
Balancing Redox Rxns1)Determine all ox #
2)Determine elements being oxidized & reduced
3)Divide rxn into half-rxns
4)Balance half-rxns
Balancing Half-Rxnsa)Balance redox elements
b)Balance ox # with e-
c)Balance e- between the two half-rxns
Balancing Half-Rxnsd)Balance total charge
with H+ or OH-
e)Balance H’s with waterf) Check balance with oxygen
Balancing Redox Rxns5) Add the two half-reactions
a)Cancel like substances from each side of the full reaction
b)Check work
