How it Tastes
Potassium bromide has different tastes depending on how much is dissolved in water.
- If you taste a very small amount, it might seem sweet.
- If there's a bit more, it can taste bitter.
- If there's a lot, it tastes salty, just like table salt.
This changing taste is mostly because of the potassium part of the compound.
How is it Made?
Scientists can make potassium bromide in a few ways.
- One way is to mix hydrogen bromide with potassium carbonate or potassium hydroxide.

What is it Used For?
Potassium bromide has several important uses.
- Medicine: It can be used as a medicine to help people or animals calm down. This is called a "sedative." It also helps stop convulsions, which are sudden, uncontrolled movements of the body. The bromide part of the compound is responsible for these effects.
