Barium hydroxide (Ba(OH)2) is a chemical compound that plays a vital role in various industrial processes. Its chemical formula is Ba(OH)2, consisting of one barium cation (Ba2+) and two hydroxide anions (OH-). This compound can undergo a redox reaction, where barium cation undergoes reduction, and hydroxide anions undergo oxidation.

Ba2+ + 2 e- → Ba0 (reduction)

2 O2- - 2 e- → 2 O1- (oxidation)

Therefore, Barium hydroxide is both an oxidizing and reducing agent.
