- Reduction is
- the gaining of electrons
- Oxidation is
- the losing of electrons
- Oxidized-
- the substrate combined with oxygen
- An element in it's free state has an oxidation of..
- Zero
- All compounds have a net..
- of zero
- Oxygen has an oxidation state of..Except in...
-
minus 2
Peroxides - Hydrogen has an oxidation state of..Except in
-
one
a hydride (minus one) - In small covelant molecules the element with the greatest...has its... as its..state
-
electronegativity,
natural ion charge,
oxidation - Da Rules for redox reaction stuff
-
1) Balance Atoms
2) Balance Electrons
3)Balance Oxygens by adding water
4)Balance Hydrogens by adding H+ - 2 most common Voltaic cells
-
1) Dry Cell - flashlight
2) Lead Storage Battery - car battery - Parts of a Lead Storage Battery
-
Anode and Cathode (terminals)
salt bridge - Anode (-)
- oxidation, dissolving occurs
- Cathode (+)
-
reduction, plating occurs
Electroplating occurs here - Most positive value will be the one that
- will be reduced
