Cobalt(II,III) oxide facts for kids
Cobalt(II,III) oxide is a special kind of chemical compound. It's made of two elements: cobalt and oxygen. Its chemical formula is Co3O4. This means each molecule has three cobalt atoms and four oxygen atoms. What's interesting is that the cobalt atoms in this compound have different "charges" or "states." One cobalt atom has a +2 oxidation state, and two other cobalt atoms have a +3 oxidation state. This mix makes it a unique compound.

What is Cobalt(II,III) Oxide Like?
Cobalt(II,III) oxide is a dark, black solid. It can react with other chemicals. For example, if you mix it with hydrochloric acid (a strong acid), it creates two new substances: chlorine gas and cobalt(II) chloride. This shows how it can change when it reacts with acids.
How is it Made?
Scientists can make cobalt(II,III) oxide by heating another compound called cobalt(II) oxide. When cobalt(II) oxide is heated to about 600 °C (1,112 °F), it changes into cobalt(II,III) oxide. If you heat it even hotter, to around 900 °C (1,650 °F), it will change back into cobalt(II) oxide. This shows that temperature plays a big role in what form the cobalt oxide takes.
What is it Used For?
Cobalt(II,III) oxide has been studied for different uses. One area of research is using it to help make hydrogen. Hydrogen is a very important element that can be used as a clean fuel in the future. Scientists are always looking for new ways to produce it more easily.
Is it Safe?
Like many chemicals, cobalt(II,III) oxide needs to be handled carefully. It can irritate your skin if it touches you. If someone accidentally swallows it, it could cause harm. It's always important to follow safety rules when working with any chemical compound.
