Electrolisis (Bicarbonate of sodium )?
Answer:
sodium bicarbonate...that's Na(2)CO(3), right?
in electrolysis, the more electronegative ions are attracted to the cathode and anode
that would be the hydrogen ion and hydroxide ion.
i don't see why the solution should turn blue
unless...what electrodes are you using to do the electrolysis?
if you are using copper electrodes, then the solution may tum blue because one of the electrodes ( i'm not sure which one) is being ionised (changing from copper to copper 2+). that would account for the blue tinge in he solution.
