this is my first comment though iam using it from 3years. hats off to you guy. more than thanks

[@valluruaiswarya1706]

sir if zn+2 gives electrons to ag then zn should become positive charge and ag should become negatively charged

[@achalkumar9078]

read the question first clearly its mentioned that which electrode is negatively charge.so answer is correct because on anode oxidation take place.memory tips loan(l_left,o_oxidation,a_anode,n_negative)

Isnt the right order mg>Al>Zn>Cu>Fe? I mean there are two Fe's in the chart

through the salt bridge Zn2+ from anode n so4- from cathode should be released ? as he said earlier in 4th lec

[@vijaynandan1857]

+Suyash parkale salt bridge is to make the electrolytic cell neutral. it has zn+2 and so4-2 ions. so at anode -ve charge is supplied to cathode so excess +charge goes and accumulates in soln. so to make neutral salt bridges sends -ve to anode.

great work

[@ilyaskhanday6715]

Little mistake is there..in 2nd question it should be in increasing order plz check the videos before uploading

[@arhamvoice4039]

sir how can i remember this chart

[@suhanamandawar8762]

good one!

[@akhilaji776]

any trick to memorize the electrochemical series?

[@VamsiKrishna-qq6xe]

Akhil Aji you need not to memorize it

[@theterminator5138]

+Akhil Aji yes bro the trick is PROFESSER S.C MAZITAL P FOR POTTASIUM S FOR SODIUM C FOR CALCIUM M FOR MAGNISIUM A FOR ALUMINIUM Z FOR ZINC I FOR IRON T FOR TIN LIKE THIS U CAN LEARN

no problem :)

[@VamsiKrishna-qq6xe]

thank you sir

[@mickeemanjot]

There are two Fe in the chart

[@prachu1205]

Exactly same confusion

[@srisrithar7466]

Cathode is negative and anode is positive

[@mozammilalam775]

sri Srithar no!!

[@queenelsa9925]

Noooooooooo!
