Question

Define redox reactions. ​

Answer 1

Answer:

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.

Answer 2

Answer:

Redox reaction:

• Redox reaction is the gain of hydrogen atoms or loss of oxygen atoms.
• Gain of electron is called reduction.
• Removal of oxygen is called reduction.
• Decrease in oxidation number is called reduction.
