Question on Oxidation

How many moles of electrons will be released by one mole of dichloroacetic acid when it is converted to chlorine, carbon dioxide and water in a reaction?


Answer:


6 moles of electrons will be released by one mole of dichloroacetic acid in that reaction. The chlorine atoms will release 2 moles of electrons as their oxidation state changes from -1 to 0 and the carbon atoms will release 4 moles of electrons as their oxidation state changes from +2 to +4.
