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).
hydrogen behave as a metal at low pressure only why
What is Dielectric loss These losses occur because of electrons hopping from one lattice site to another in transition metal oxides.

Q. Isomerism in Coordination Compounds? You have already learnt about isomerism in your earlier studies. The phenomenon of isomerism is not restricted to organic compounds only
first law of crystallography
The ph of an aqueous solution of Ba(OH)2 is 10 if the ksp of Ba(OH)2 is 1*10^-9 then the concentration of Ba+2 ions in the aqueous solution is Ans) [OH(-)] = 10^(-4) 2.
