Redox Reactions |
Two Half Reactions
OIL-RIG
Oxidation- Loss of Electrons Reduction- Gain of Electrons |
|
|
Respiration |
Oxidation and Reduction coupled with a gradient |
|
|
Arobic Bacteria |
Has Oxygen to function
Ferous Iron (Fe II) loses an electron and gives it to oxygen (O2) which Makes Feric Iron ( orange colored) and causes rust
Iron Oxidizing |
|
|
Anerobic Bacteria |
Without Oxygen
Hydrogen ( H2) loses and electron and becomes ( H3) giving the electron to the Feric Iron (Fe III) thus making it Ferous Iron (Fe II)
this creates the metallic iron
Iron- reducing |
|
|
Donor |
Gives Electrons Away
|
|
|
Acceptor |
Takes Electrons
|
|
|
Oxygen |
A strong reducer - likes to gain electrons ( high potential acceptor)
positive number on the scale ( gains electrons)
will cause a large voltage difference when combine with a strong donor
Yeilds a lot of energy
Poorly soluble in Water and diffuses slowly
|
|
|
Lithautotrophs |
Lith- Inorganic Auto- can use CO2 in air to build organic compounds
Rock eater
|
|
|
bateries
|
Redox Reaction
Donors must have lower potential than their acceptors
|
|
|
Voltage negative |
Loses Electrons
electrons move from solution to silver Electron donor and low potential to be electron acceptor Push electrons onto the silver |
|
|
Voltage positive |
Gains Electrons electrons move from silver to solution has high potential to be an electron acceptor |
