2.2.1 Construction of Redox Equations
The main idea is that any redox reaction can be split into two parts: an oxidation half-reaction (where electrons are lost) and a reduction half-reaction (where electrons are gained). The overall redox equation is simply the sum of these two half-reactions. To construct the final equation, y
