Barium hydroxide facts for kids
Barium hydroxide is a special chemical compound. Think of it as a tiny building block made of different parts. Its chemical formula is Ba(OH)2. This means it contains barium and hydroxide ions, which are tiny charged particles.

What is Barium Hydroxide?
Barium hydroxide is a white, solid substance. It looks a bit like a white powder or small crystals. When you mix it with water, it dissolves. This creates a basic solution. A basic solution feels slippery and can be used to neutralize acids.
How Barium Hydroxide Reacts
Barium hydroxide is quite reactive. It can change when heated or when it meets other chemicals.
- When heated very strongly, it breaks down. It turns into barium oxide.
- It reacts with carbon dioxide gas. This reaction forms a new substance called barium carbonate. Barium carbonate is a white solid.
- It also reacts with substances called sulfates. This reaction creates barium sulfate.
- If it meets hydrogen sulfide, it forms barium sulfide.
How is Barium Hydroxide Made?
Making barium hydroxide is quite simple. Scientists create it by dissolving barium oxide in water. This process causes the barium oxide to react with the water. The reaction then forms barium hydroxide.
What is Barium Hydroxide Used For?
Barium hydroxide has several important uses. It is especially helpful in chemistry and for cleaning.
Using Barium Hydroxide in Experiments
One main use is in a process called titration. Titration is a way to find out how much of a certain substance is in a solution.
- Sometimes, other chemicals like sodium hydroxide are used in titrations.
- However, sodium hydroxide can sometimes have impurities. These impurities can make the results wrong.
- Barium hydroxide is better because it reacts with these impurities. It turns them into a solid that can be easily removed. This helps make the titration results more accurate.
Other Practical Uses
Barium hydroxide is also a very strong base. This makes it useful in many areas.
- It is used in organic chemistry. This is a branch of chemistry that studies carbon-containing compounds.
- It can help clean up spills of strong acids. For example, it reacts with sulfuric acid to form barium sulfate. This makes the acid less dangerous.
- It can even help remove ink marks from clothes!
Safety First: Handling Barium Hydroxide
It is very important to be careful with barium hydroxide.
- It is a corrosive substance. This means it can cause damage to skin or other materials. This is because it is a strong base.
- It is also toxic. This means it can be harmful if swallowed or if it gets into the body. This is due to the barium ions it contains. Always handle it with proper safety gear.
