Scribe - feb 28

All we did on wednesday was that we went over the "oxidation and Reduction" hand out that Ms K gave us last week. We went over assigning oxidation numbers and then we had time to work on identifying the reducing agents and oxidizing agents.

here's an example:

FeBr₂ + Br₂ ----> FeBr₃

Fe⁺²Br^-1₂ + Br⁰₂ ----> Fe⁺³Br^-1 ₃ ' identifying the oxidation numbers

Fe loses one electron therefore it is oxidized

Br gains one electron therefore being reduced

FeBr is the reducing agent
Br₂ is the oxidizing agent

Tip:

if one has gained an electron then it's reduced
if one has lossed an electron then it is oxidized
an agent is found on the left side of the arrow ( ----> )

remember that our test tube mystery lab is due on monday
