In electrolysis where the reaction start first, at anode or at cathode?
Answer:
reaction is simulataneous at both the electrodes
negative to positive. negative e- electrons are free to move about.
uh, cathode ray tube experiment, clearly shows the negative charges move more frequently. even though there are some positive ions that move the other way. when using electrolysis, the platted object increases in mass while the other half of the reaction loses matter. Just take a look at copper plating, or chromate plating processes.
Both at a time they start moving
they both have to happen - if the cathode won't reduce then there is no drive for the anode to oxidize. If the anode won't oxidize, then the the cathode can't get reduced.
Because of dynamic equilibrium, both of these things are already happening in each of the electroyltic cells even before you hook the two cells together!
