Hypo is used to remove excess chlorine from Fabric in textile industry where chlorine oxidises Hypo to a single product. In this reaction the change in the oxidation state of terminal Sulphur of hypo is

The products obtained by passing chlorine through hypo solution are

Cl_(2)+H_(2)S to 2HCl+S , In that above reaction oxidation state of chlorine changes from

Oxidation and reduction process involves the transaction of electrons. Loss of electrons is oxidation and the gain of electrons is reduction. It is thus obvious that in a redox reaction, the oxidant is reduced by accepting the electrons and the reductant is oxidised by losing electrons. The reactions in which a species disproportionates into two oxidation states (lower and higher) are called disproportionation reactions. In electrochemical cells, redox reaction is involved, i.e., oxidation takes place at anode and reduction at cathode. Detennine the change in oxidation number of sulphur in H_(2)S and SO_(2) respectively in the following reaction: 2H_(2)S+SO_(2) to 2H_(2)O+3S

Chlorine dissolves in water to form a mixture of hydrochloric acid and hypo chlorous acid. What is the equivalent weight of chlorine in that reaction

Chlorine is used to purify drinking water. Excess of chlorine is harmful. The excess of chlorine is removed by treating with sulphur dioxide. Present a balanced equation for this redox change talking place in water.

Bleaching of a fabric cloth is done using A and excess of chlorine is removed using B.A and B are :
