The electrode potential is an intensive property whose value is independent of the amount of species in the reaction. Thus, the electrode potential for the…

A cell electromotive force (or “emf”) is a measure of the driving force of the electro-chemical cell reaction. The reaction at the anode has a…

We know that the charge of one electron is 1.60 x 10-19 C. Thus, the charge carried by one mole of electrons will be 6.02…

The amount of work done in moving an electrical charge through a conductor from a point of high electrical potential (or high electrical pressure) to…

Normally the potential difference (voltage) measured across the electrodes is less than the maximum possible voltage of the cell. This is because the actual flow…

Potential difference is the difference in electric potential (also referred to as electrical pressure) between two points. This difference in electrical potential can be measured…

It is easier to have a shorthand way of writing out particular electrochemical cells. A cell consisting of the zinc-zinc ion half-cell and the copper-copper…

It is important to Know that the zinc electrode gradually gets smaller, as it reacts to form zinc ions in solution. Similarly, the copper electrodes…

The applications of Electro-Chemistry and related reactions range from the lead-acid batteries in cars to torch batteries as seen below. Electro-chemical Cells An electro- chemical…

Simple hydrocarbons for use as refrigerants are comfortably inside it. There has been a move towards hydrocarbons and away from chlorofluorocarbons (CFCs) as refrigerants because…
