Isn't biology wonderful?... dcox 2010-05-27T12:03:41+00:00 http://www.sutsci.org/a2chemistry/archives/000901.html hope this helps...

In building cells two couples are required with different values of redox potential. One couple... dcox 2010-05-12T13:31:34+00:00 http://www.sutsci.org/a2chemistry/archives/000238.html Although it is not difficult to measure relative half-cell potentials, it is impossible to determine absolute half-cell potentials because all voltage measuring devices measure only differences in potential. To measure the potential of an electrode, one contact of a voltmeter... dcox 2010-05-12T13:29:08+00:00 http://www.sutsci.org/a2chemistry/archives/000391.html Using redox chemistry as a source of mobile electrical energy is inspired! I mean..without this you'd NEVER be able to say "I'm on the train...!". Two half equations with different E^o values is all that it takes. Thes can be... dcox 2010-05-12T13:28:02+00:00 http://www.sutsci.org/a2chemistry/archives/000242.html This is a further use to which a table of redox potentials may be put. To do this you need to adopt a specific protocol, which once mastered is easy to follow. Start by reading the question carefully and combine... dcox 2010-05-12T13:27:48+00:00 http://www.sutsci.org/a2chemistry/archives/000241.html Two couples with different electrode potentials may be combined to build a cell, a device to physically separate the oxidation from the reduction so that when the electrons move from one process to the other they pass through the external... dcox 2010-05-12T13:26:04+00:00 http://www.sutsci.org/a2chemistry/archives/000899.html Please open this.....
