Agronomists are probably depriving themselves of a key factor in crop and soil science which could be a …

What is redox in chemistry. Things To Know About What is redox in chemistry.

A redox is a type of chemical reaction that involves a transfer of electrons between two species. The oxidation state of an element corresponds to the number of electrons, that an atom loses, gains in a chemical reaction. The reducing agent is the reactant that is being oxidized. The oxidizing agent is reactant that is being reduced.May 26, 2023 · Example of Redox Reactions. 2Cu2O (s) + Cu2S (s) → 6Cu (s) + SO2(g) Oxidizing or reducing agent in a chemical reaction, is typically identified by its oxidation state. An oxidant is a substance that causes oxidation by accepting electrons, while a reductant is a substance that causes reduction by donating electrons. Another example of a redox reaction is this combination (synthesis) reaction between magnesium and chlorine. M g lost electrons, so this is an oxidation reaction.
