what is the oxidzing agent in the following: A topscore gchem Q
PbO(s) + CO--->Pb + CO2.

Isn't Pb loosing the Oxygen becoming the substaqnce oxidized and the reducing agent. CO is gaining another O, is reduced and the oxidizing agent..

Answer says.. OXIDIZING AGENT IS PbO???

Oxidizing agents are reduced.

In PbO, the O has a -2 charge, and the Pb has a +2 charge.

So when the Pb +2 in PbO becomes Pb, its gaining electrons, and thus PbO is the oxidizing agent.

Hope that was helpful!

Dude I think your getting it mixed up with the Organic chem Oxidized and Organic chem Reduced. In organic, if you MAKE a C-O bond go to a C=O bond, you are OXIDIZING. If you are making a C=O bond go to CH2 you are reducing. Go look it up in McMurrays, just gotta read the summary page of the section.

PbO O is -2, making Pb +2. on the product side Pb went from +2 to neutral, that means it gained 2 electrons. Oxidizing agent means it reduces itself. Oil Rig, reducation is to gain electrons. DocHowell is on the money. I am pretty sure that's the answer based on what I learned

thanks makes sense.. but really have to locate yourslef on the periodic table with these problems.

OR....think of it like this. PbO loses an OXYGEN so it is reduced and hence the oxidizing agent.
