5.)Shortly after the dissolution of lead(IV) oxide, the dissolved Pb will react with water to form dissolved species and according to the following stoichiometric equation and chemical equilibrium coefficients. This will continue pulling PbOz29) into solution, causing higher overall lead concentrations. What are the molar concentrations of the three dissolved lead species (Pb.r, PbO,, and PbO.+) at pH 11? If you convert the sum of these concentrations to µg/L as Pb, does it exceed the EPA limit of 15 µg/L? Pb+ + 3H20= (PBO3)²- + 6H+ pKeg = 23.04 Pb4+ + 4H2O = (P6O4)4- +8H+ pKeg = 63.8

Shortly after the dissolution of lead(IV) oxide, the dissolved
Pb4+ will react with water to form dissolved species
and according to the following stoichiometric equation and
chemical equilibrium coefficients. This will continue pulling
PbO2(s) into solution, causing higher overall lead
concentrations

5.)Shortly after the dissolution of lead(IV) oxide, the dissolved Pb+ will react with water to form dissolved species and according to the following stoichiometric equation and chemical equilibrium coefficients. This will continue pulling PbOze) into solution, causing higher overall lead concentrations. What are the molar concentrations of the three dissolved lead species (Pb., PbO, and PbO.+) at pH 11? If you convert the sum of these concentrations to ug/L as Pb, does it exceed the EPA limit of 15 µg/L? Pb4+ + 3H20 = (P6O3)²- + 6H+ pKeg = 23.04 Pb4+ + 4H2O = (P6O4)4- + 8H+ pKeg = 63.8
