WebThe modern chemical definition of reduction is when a compound gains one or more electrons. It is therefore the opposite of oxidation, where a compound loses one or more electrons. One of the earliest named reactions featuring reduction is the Tishchenko reaction, named after the Russian organic chemist Vyacheslav Evgen'evich Tishchenko. WebPYREX™ Deluxe Microchemistry Kit.
