need help in reactivity series of metals
« on: March 27, 2004, 12:49:11 PM »
Help please. Is gold or platinum less reactive? If gold is less reactive, why is platinum (relatively more expensive) used as the common inert electrode in electrolysis? What is the least reactive of all metals? Where could I get the reactivity series of all metals?
I would appreciate if some 1 could help me with my problems. Thank you.

Well, platinum has some interesting catalytic properties not found in gold that are very useful in industry.  It is usually used as the inert electrode... as to why we don't use gold... I'm not sure.  However, you can got to http://www.webelements.com for more information about the reactivity of metals; just click on the reduction potentials and look for the metal ion alone.  To your right you'll find that you can look up the same properties for a metal in the same area under "Go to Adjacent".

If you need more information about interpreting the info, please repost.
