In an electrochemical cell a redox reaction perform in two halves. Electrons are liberated by the oxidation half reaction at one electrode and go through an electrical circuit to another electrode where they are used for the reduction. The cell potential E is the potential difference between the two electrodes have to balance the thermodynamic tendency for reaction, so that the cell is in equilibrium and no electrical current flows. E is related to the molar Gibbs free energy change in the overall reaction according to
where n the number of moles of electrons passed per mole of reaction and F is the Faraday constant (9.6485×104 C mol-1).
Classification of Coordination Compounds Since the number of known complexes is so large, we need to classify and categorise them in order to study their chemistry systematica
describe exothermic and endothermic reactions with examples.
Consider the ground state of(Z= 24) . The numbers of electrons with the azimuthal quantum numbers,l=1 and 2 are, respectively: (1) 16 and 4 (2) 12 and 5

Vinegar, orange juice, and battery fluid are familiar acids. Different acids have different acid strengths. Some characteristics of acids are: They taste sour.
why C-12 is taken as standard for atomic mass?
Many ionic crystals dissolve in water because: (1) Water is an amphiprotic solvent (2)Water is a high boiling liquid (3) The process is accompanied by a positive heat of
Q. Determine the Uniqueness of Carbon? Ans. Carbon forms a very large number of compounds--over 4,000,000. This is far more than the number of compounds of all other eleme
