since the hydroxide ions form near the cathode .... they attract the sodium ions and form at the cathode.....
.....dont have to know in detail though....
water gains electrons from the cathode ,,, therefore reduction takes place as u said .....
thanks a lot esso
+ rep for u
however dude i dont get it why do de hydroxide ions form near the cathode shudnt dey be attracted to de anode dats wat i dont undersatdn
i understand dat sodium ions are formed near de cathode since dey are attracted to the cathode as they are positive ions
nd dude y does water gain 2 electrons to form hydroxide
shudnt water naturally dissociate to form the hydrogen ions and hydroxide ions
because we have never been taught about water gaining 2 electrons from de cathode to form de hydroxde ions + hydrogen
we have been told dat water dissociates to produce hydrogen ions _ hydroxide ions
nd for hydroxide weve learnt that
4OH- = 2H20 + O2 + 4 electrons
can u please help as to why water gains two electrons from the cathode?
