Reactivity of any element towards any other is extremely dependent on conditions, mainly temperature, concentration and pressure. Put like you did
your question is more or less meaningless...aeacfm - 23-5-2011 at 13:40
ok , during electrolysis of brine (sodium chloride 3 %) using carbon electrodes i found in the anodic area particles like carbon ( great amount and c
electrode continued in producing these particles during electrolysis) i surprized as i know that c electrode is corrosion resistant ? so is this
corrosion or erosion or what?if so what is the corrosion products

ok now i could help you , no the carbon only get to fine powder , it doesn't react.aeacfm - 23-5-2011 at 14:03

C get to fine powder so this is erosion ! isnt it ScienceSquirrel - 23-5-2011 at 14:15
Sometimes undefined reactions can occur to form minor products with break up of the material.
Chemists like defined reactions with discrete reactants and products but things are not always like that.LanthanumK - 23-5-2011 at 15:45
Every time I use carbon rods for electrolysis more than a few hours, they start eroding.aeacfm - 23-5-2011 at 15:58

in brine electrolysis it is only few minutes IrC - 23-5-2011 at 18:21
I think consideration should be given to possible binders (if any) used to make a rod from the carbon. Clay is used as a binder to make a graphite rod
called a pencil as example. Depending upon your source of carbon rods I would think the possibility that the binder is being eroded should be
considered. I ran into this using rods scrapped from dead batteries once upon a time.

i use the same source of carbon electrode , so not carbon it self it is only the binder which eroded
but for carbon electride with no binders will this erosion happen
