Write reaction occuring during the electrolysis of agno3
Answers
An aqueous solution of AgNO3 with platinum electrode.
as you know, Platinum is an inert electrode so, at anode oxidation of water takes place. as a result of this O2 is released at anode according to below equation
2H2O(l) -------> O2 + 4H+ + 4e
at cathode reduction of Ag+ ions takes place
therefore , on electrolysis of aqueous solution of AgNL3 solution with platinum electrode , O2 is released at anode and Ag+ ions deposited at cathode.
You would get silver at the cathode, and oxygen at the anode.
Since silver is below hydrogen in the spectrochemical series,it tends to get reduced over hydrogen, similarly, since NO3−NOX3X− is above OH−OHX− , it tends not to get oxidised, therefore giving oxygen.
Ag++e−⟶AgAgX+eX−⟶Ag (at cathode)
4OH−⟶O2+2H2O+4e−4OHX−⟶OX2+2HX2O+4eX− (at anode)
