Hydrobromic acid facts for kids
Hydrobromic acid is a very strong acid. Its chemical formula is HBr. This means it is made of one hydrogen atom and one bromine atom. It is a clear, colorless liquid that can be very corrosive.

What is Hydrobromic Acid?
Hydrobromic acid is known as a "strong acid." This means it easily gives away its hydrogen protons when it's in water. Because it's so strong, it can react with many other chemicals. It is similar to other strong acids like hydrochloric acid.
How is Hydrobromic Acid Used?
Hydrobromic acid is very useful in chemistry. Its main job is to help make other chemicals called bromides.
Making Bromides
- Reacting with Metals: When hydrobromic acid touches certain metals, it reacts to form bromides. For example, it can react with zinc to make zinc bromide.
- Reacting with Metal Oxides: It also reacts with metal oxides. These are compounds where a metal is combined with oxygen. When hydrobromic acid reacts with them, it forms a bromide and water.
These bromides are then used to make many different products. They can be found in medicines, dyes, and even some photographic chemicals.
How is Hydrobromic Acid Made?
Scientists and companies make hydrobromic acid in several ways. These methods involve combining different chemicals to create HBr.
Making it from Bromine
One common way to make hydrobromic acid is by mixing bromine, sulfur dioxide, and water.
- When these three chemicals are put together, they react.
- This reaction creates two acids: hydrobromic acid (HBr) and sulfuric acid (H₂SO₄).
Dissolving Hydrogen Bromide
Another simple way to get hydrobromic acid is by dissolving hydrogen bromide gas in water.
- Hydrogen bromide (HBr) is a gas at room temperature.
- When this gas dissolves in water, it forms the liquid hydrobromic acid.
Other Methods
- Using Sulfur and Phosphorus: Hydrobromic acid can also be made by reacting bromine with sulfur and phosphorus. This is a more complex chemical process.
- Electrolysis: Sometimes, it's made using electrolysis. This is a process that uses electricity to cause a chemical reaction in a solution containing bromides.
- Non-Oxidizing Acids: It can also be made by reacting bromides with acids that are "non-oxidizing". This is important because if an oxidizing acid were used, it would change the bromides into bromine instead of making hydrobromic acid.
Safety with Hydrobromic Acid
Because hydrobromic acid is a strong acid, it must be handled very carefully. It can cause serious burns if it touches skin or eyes. People who work with it always wear special safety gear, like gloves and eye protection.
