For the electrolysis of molten potassium bromide:
(a) write the equation for the reaction at cathode.
(b) write the equation for the reaction at anode.
(c) write the equation for the overall reaction.
Please answer for me
Any answer
Potassium is the ectrolyte in this reaction
To answer the question, we need to understand the process of electrolysis and the properties of potassium bromide.
(a) The reaction at the cathode:
During electrolysis of molten potassium bromide (KBr), the positive potassium ions (K+) migrate towards the cathode (negative electrode). At the cathode, the potassium ions gain electrons and are reduced to form potassium metal (K):
2K+ + 2e- → 2K
(b) The reaction at the anode:
At the same time, the negative bromide ions (Br-) migrate towards the anode (positive electrode). At the anode, the bromide ions lose electrons and undergo oxidation to form bromine gas (Br2):
2Br- → Br2 + 2e-
(c) The overall reaction:
To determine the overall reaction, we combine the individual reactions at the cathode and anode:
2K+ + 2Br- → 2K + Br2
So, the overall reaction is:
2KBr → 2K + Br2
KBr -------> K+ and Br- ions.
at anode (oxidation takes place by de electronation process)
well thats for a only <D
good luck finding someone that knows b and c ;_;
