Ok, and in this “reduced reaction”, Barium Fluoride would not be considered an ‘oxide’.. ? correct ?       -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Howard Wu Sent: Wednesday, September 17, 2003 8:40 PM To: Charles R.

Strictly speaking oxidation is the loss of electrons.  The electrons need somewhere to go so something is going to gain electrons and that is the reduction part.  So to undergo oxidation, something has to be reduced - usually it's oxygen that accepts the wayward electrons but it doesn't always have to be so. For example: Ba + F2 -> BaF2 is an oxidation-reduction reaction that doesn't involve oxygen.  Here F is the oxydizing agent. Steven Steven Singletary 54-1224 Dept.
