Barium Peroxide

aBarium peroxide, known by its chemical formula BaO2, is an inorganic compound that typically appears as a white solid (though it can turn gray due to impurities). It is widely recognized as one of the earliest peroxide compounds discovered and is commonly used as an oxidizing agent. When ignited, like other barium compounds, it emits a striking green color, making it useful in fireworks. Historically, it has also been utilized as a precursor for producing hydrogen peroxide.
