Question
Chapter 22, Problem 24RE
Interpretation Introduction
Interpretation:
The statement “chlorophyll molecules transfer one electron. However, oxidation of water needs four electrons” is to be explained.
Concept Introduction:
Oxidation is the addition of an electronegative element or the removal of an electropositive element in a
Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction.
The chemical reaction in which oxidation process and reduction process takes place and reduction take place simultaneously is called a
