- What is the empirical formula of Compound A?
PbCl 4
- What is the empirical formula of Compound B?
PbCl 2
- Write the equations for the experiment and then identify what is being oxidized and what
is being reduced.
PbCl 42 "PbCl +Cl 2
Oxidation: Chlorine (from −1 to 0)
Reduction: Lead (from +4 to +2)
PbCl 22 ++H "Pb 2 HCl
Oxidation: Hydrogen (from 0 to +1)
Reduction: Lead (from +2 to 0)
