passage is blocked‚ but gas from the fermenting chamber will be able to push the water out of the way and escape (brewers call this an airlock). This setup excludes air (and oxygen) from the system (which allows anaerobic oxidation) and prevents further oxidation (by aerobic oxidation) of the ethanol to acetic acid. Label the fermentation setup with your name and place the flask in the incubator chamber Isolation by Fractional Distillation Do not shake the flask; avoid disturbing the sediment on

reduction potential of +.337 V. Copper was reduced in every reaction‚ also proving that it was the strongest oxidizing agent. The electrode with the most positive oxidation potential in its half reaction had reacted as the best reducing agent‚ or was more likely to be oxidized. The best reducing agent in this experiment was Mg‚ with a oxidation potential of 2.37 V. This was also proven in the experimental results‚ the reaction between copper and magnesium had yielded the highest voltage. The second

photophosphorylation – occurs in photosynthetic cells‚ which contain light-trapping pigments (chlorophyll); light cause chlorophyll to give up electrons. Energy released from the transfer of electrons (oxidation) of chlorophyll thru a system of carrier molecules is used to generate ATP. c) Oxidation – the removal of electrons d) Chemiosmosis – process whereby energy is released when protons moves along a gradient and is used to synthesize ATP; responsible for most of the ATP generated; process

Chem Factsheet September 2002 Number 37 Redox Equilibria I: Standard Electrode Potentials and Cells To succeed with this topic you need to: • be familiar with the concept of equilibrium (Factsheet 09); • be able to assign oxidation numbers to elements (Factsheet 11). After working through this Factsheet you will: • understand the link between cells and oxidising and reducing powers (redox reactions); • have met the Standard Hydrogen Electrode and why it is needed; • know the definition for Standard
