IN ELECTROCHEMISTRY THERE IS NOTHING THAT MUCH SPECIAL

BUT THOSE WHICH U SHOULD GO THROUGH ARE :-

1.. RULES FOR ASSIGNING OXIDATION NUMBER

▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪

2.. NO NEED TO REVISE BALANCING EQUATIONS BECAUSE THEY ARENOT GIVEN IN PAPER.

▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪

3.. REVISE FARADAY'S LAW .

▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪

4.. LEARN STANDARD ELECTRODE POTENTIALS OF ELEMENTS WHICH ARE GIVEN IN UR BOOK FOR EXAMPLE:-

E red VALUE OF Cu IS POSITIVE THAT IS +0.34 V

THAT OF MAGNESIUM IS _2.38V

AND THAT OF ZINC IS _0.76 V , , THEIR OXIDATION POTENTIAL WILL HAVE SAME VALUE BUT WITH OPPOSITE SIGN .

5.. LEARN DEFINITIONS OF ELECTROCHEMICAL CELLS THEIR EXAMPLES

▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪
