Question

what happens at the anode?

Answer 1

oxidation...

Answer 2

do you mean in electrolysis or in galvanic cell? in electrolysis anode is positive (+) so there you have oxidation and in galvanic cell you have reduction cause there anode is negative

Answer 3

yes you hav to describe the conditions if it is during electrolysis then positive ions move towards anode and gain an electron and thus reduced

Answer 4

@Goutham is right.
Whatever the case, oxidation takes place at the anode.

@warz: "positive ions move towards anode" No, they don't. In a galvanic cell cations (positive) move to the cathode and anions (negative) to the anode; that is where their names come from.

Answer 5

thanks for correcting me but can you please explain to why the negative ions are moving towards anode its confusing they should be attracted towards the positive cathode but i do totally agree with you

Answer 6

warz i think its from "ancient" times (1700...) when electricity was barely known, and then they thought that positive particles, for which we now know are protons, carry the charge, so in galvanic cell cations (positive ions) which are going to cathode and anions (negative ions) are going to anode which is negative. but cause they thought that positive particles carry electricity cation which in galvanic cell receives electron (they thought proton +) and begins to deposit on cathode... i hope i didn't mess it up a lot cause english is not my primary language

Answer 7

In a galvanic cell, the anode is the electrode linked to the positive terminal of the battery and the cathode is the electrode linked to the negative terminal.

In a battery, this is the other way round : cathode is positive terminal of your battery and anode negative terminal.

In any case (galvanic or battery), anode is where the oxidation takes place and cathode where the reduction takes place.

Answer 8

anion = -ve
anode = +ve
cation = +ve
cathode=-ve

Answer 9

Thank you every one my concept is clear now :D
