I(2)+S(2)O(3)^(2-) to I^(-)+S(4)O(6)^(2-...

`I_(2)+S_(2)O_(3)^(2-) to I^(-)+S_(4)O_(6)^(2-)`

A

its molecular weight

B

1/2 of its molecular weight

C

1/4 if its molecular weight

D

twice of its molecular weight

Text Solution

Verified by Experts

The correct Answer is:
B
Here the oxidation state of `I_(2)` change form O to - 1 but in .1. mole of `I_(2)`. two iodine atoms are there so the total change in oxidation number is .2.
`E.W=(M.W)/(2)`

A constant current was flown for 2 hour through a solution of KI At the end of experiment liberated lodlne consumed 21.75 mL of 0.0831 M solution of sodium thiosulphate followihg the reaction: I_(2)+2S_(2)O_(3)^(2-) to 2I^(-) +S_(4)O_(6)^(2-) . What was the aveagre rate of current flow in ampere?

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. In the reaction: I_(2)+2S_(2)O_(3)^(2-) to 2I^(-)+S_(4)O_(6)^(2-)
