reactions. All chemical reactions where the oxidation numbers of atoms are changed are called redox reactions. Acid-base reactions hold similar characteristics that redox reactions do. Basically‚ redox reactions can be described as a group of reactions that focus on the transfer of electrons. Similarly to acid-base reaction‚ a reduction reaction must be happening simultaneously with an oxidation reaction (Masterton‚ 2008). A loss of electron is called oxidation while reduction is an increase of electrons

ADJIVON UNIT 1 INTRODUCTION Organic chemistry started as the chemistry of life‚ when that was thought to be different from the chemistry in the laboratory. Then it became the chemistry of carbon compounds‚ especially those found in coal. Now it is both. It is the chemistry of the compounds of carbon along with other elements

electrolysis‚ or if a voltage is created by a chemical reaction as in a battery‚ it is an electrochemical reaction. In contrast‚ chemical reactions where electrons are transferred between molecules are called oxidation/reduction (redox) reactions. In general‚ electrochemistry deals with situations where oxidation and reduction reactions are separated in space or time‚ connected by an external electric circuit to understand each process. |Contents
