# Thread: Difference between caustic soda and caustic potash

1. I read the chemical formula for Potassium Hydroxide (Caustic soda)=NaOH (1)

I also read the chemical formula for caustic potash having same chemical name Potassium Hydroxide =KOH.

I want to know what is the difference between these two chemical compounds in terms atoms, molecules, ions?

Why the name of (1) is not Sodium Hydroxide as it contains sodium(Na)?

2.

3. It looks like a typo in your book. The name of $\ce{NaOH}$ is indeed , also known as lye and caustic soda.
