In many species, a transition metal has an unusually high or low oxidation state. Write balanced equations for the following and find the oxidation state of the transition metal in the product:(e) Barium peroxide reacts with nickel(II) ions in basic solution to produce BaNiO₃.

Respuesta :

Barium Peroxide is an odorless, grayish-white powder. It is used as a bleaching agent, in making Hydrogen Peroxide, aluminum welding and textile dyeing. * Barium Peroxide is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, DEP and EPA.

How do you make BaO2?

Barium peroxide can be made by the reversible reaction of O2 with barium oxide. The peroxide forms around 500 °C and oxygen is released above 820 °C. A different, aqueous preparation is performed through a metathesis reaction with barium nitrate and hydrogen peroxide: Ba(NO3)2 + H2O2 ⇌ BaO2 + 2HNO.

Is BaO2 amphoteric oxide?

BaO2 is a peroxide. Barium has an oxidation state of +2 so the oxygen atoms have oxidation state of -1. As a result, the compound is a peroxide, but more specifically referred to as barium peroxide. An amphoteric solution is a substance that can chemically react as either acid or base.
