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

If 0.5 mol of BaCl 2 is mixed with 0.20 mol of Na 3 PO 4 , the maximum amount of Ba 3 (PO4) 2 that can be formed is 3 BaCl 2 + 2 Na3PO 4 = Ba 3 (PO4) 2 + 6NaCl Here cle
The pH scale: The equation: p Kw =14.00=pH+pOH is obtained by taking the negative logarithm to the base 10 of the autoprotolysis equation, where In general pX denotes -
