Mnemonics For Electrochemical Series

SHORTCUT TO THE ELECTROCHEMICAL SERIES

Hello again. I am back with a new blog. Its not because I need to but because I couldn't resist writing one. I'll provide you a simple mnemonic for remembering THE ELECTROCHEMICAL SERIES.
A series of elements we come across time and often. And a must memorize part of High School. Remember the time you woke up whole night remembering it and the next morning the elements go upside down. The next day you bought a huge chart and stick on your bedroom but still had the confusions. Now Now dont worry I'll provide you with a sentance to remember it.Details below:

Mnemonic	Elements	Electrode potential	Mnemonic	Elements	Electrode potential
Little	Lithium	-3.050	Come	Copper	+0.153
Pop	Potassium	-2.925	My	Mercury(Hg)	+0.771
Barry	Barium	-2.900	Sister	Silver(Ag)	+0.789
Canadian	Calcium	-2.870	Play	Platinum	+1.188
Star	Sodium	-2.714	Golf	Gold	+1.520
Made	Magnasium	-2.370
All	Aluminium	-1.660
Zebra	Zinc	-0.763
In	Iron	-0.440
Town	Tin	-0.136
Like	Lead	-0.126
His	Hydrogen	+0.00
Car	Copper	+0.153

Remember: Electrode potentials are reduction potential at 298K.
Now the sentence is LITTLE POP BARRY CANADIAN STAR MADE ALL ZEBRAS IN TOWN LIKE HIS CAR. COME MY SISTER PLAY GOLF .Practice this and u will b perfect in no time.
now lets talk in brief about its application

• Calculation of standard cell potential by Ecathode-Eanode. Remember First element in series become anode.
• Predict oxidizing and reducing agent. lithium is strongest Reducing agent in solution.Remember Oxidizing agent undergo reduction at Cathode and Reducing agent undergo oxidation at anode. If u r still confuse which occurs where, then i have the solution of that too. Remember two animals RED CAT(Reduction cathode) and AN OX(Oxidation anode).
• Predict dirextion of displacement. Upper in Series displace the lower one from their solution. Thats why u cannot stir copper sulphate solution with zinc spatula.
• Metals above hydrogen can form the gas when treated with non oxidising acid.

Elements on Left side except copper can form Hydrogen.
Remember this few tips and ur perfect. That's its folks. See u next time. Ans at last


do hit those like and suscribe buttons I appreciate it.
