The Short Answer

Yes, bicarbonate of soda and baking soda are exactly the same thing.

Both names refer to the same chemical compound: sodium bicarbonate (NaHCO₃).

The only real difference is what people call it depending on where they live:

Baking soda is commonly used in the United States and Canada

Bicarbonate of soda (or bicarb) is used in Ireland, the UK, and other regions

Why the Confusion Happens

The confusion usually comes from regional language differences rather than any real chemical distinction.

For example:

An American recipe might say “add 1 teaspoon of baking soda”

An Irish or British recipe might say “add 1 teaspoon of bicarbonate of soda”
