Question

reduction is loose of electrons ​

Answer 1

Answer:

In this reaction the lead atoms gain an electron (reduction) while the oxygen loses electrons (oxidation). Magnesium loses electrons and is therefore said to be "oxidized", whereas the chlorines gain electrons and are said to be reduced. ... The copper "half-reaction" is classified as reduction since it gains electrons.
