Demonstration of the colour change that accompanies the oxidation of an alcohol by potassium dichromate solution (K2Cr2O7, orange). The dichromate turns green (right) as oxidation of the alcohol (turning it into a carboxylic acid) occurs, along with the reduction of the chromium (Cr). The ...

Reactant: Reactants are the materials that start a chemical reaction. They are changed via exchange of electrons to create the products, or what you end with. Fun Facts Number of electrons in the valence shell determines the likelihood that an atom will form a chemical bond with another atom...
The oxidation number is also known as the oxidation state. It states the number of electrons an element shares in an atom. It is also defined as the charge of an ion. The oxidation number is used in REDOX reactions. In those reactions, we determine the oxidation state of each atom to ...
