Hi,
can anyone please help me with this? i have no clue how to define
if a reaction is Oxidation reduction or not. Thanks a lot
OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
