just draw a line. the soft, silvery-grey trail of pure carbon found in pencils consist of stacked up stacked sheets of interlaced carbon atoms. if these sheets are separated into films of carbon just one atom thick then you have a material called graphene, whose properties mimic those of exotic substances...
phenols) are generally harmless, mostly carbon dioxide and water. extremely high oxidation-reduction potential of the water directly in the anode chamber and meta-stable compounds of active chlorine and active oxygen participating in the reactions prevent the formation of toxic chlorine-organic substances...
