Electrolytic cell .... class12th (electrochemistry)💟

Now we know about... electrolytic cell 📲..the device which is used to convert electrical energy to chemical energy 😌......this is called electrolytic cell..

External source of voltage is used to bring about a chemical reaction....

Electrolysis:-electrolysis, process by which electric current is passed through a substance to effect a chemical change. The chemical change is one in which the substance loses or gains an electron (oxidation or reduction). 

Uses:- 

For  copper purification🏵️

I think everyone know about how to collect pure copper..but I believe you . You every thing forgot 🙂 about electrolysis.. don't worry baccha loga I explain you ... what is purification of copper ? you can easily seen in figure... 

Frist we take 2 copper rods one is pure and other one is impure.....we dip in a copper sulphate (CuSo4)💟 we connect these two rods in a battery and Cu2+ ions. attract 2e- and forms Cu....now tha cathode rod have thick than anode rod because tha impurity of anode rod mix in CuSo4 solution and Cu attach in pure copper rod ( cathode) ......now we have pure copper 😌🙌..........

Thank you ❤️....
