Negative pH

Postby Samuel G Rivera - Discussion 4I » Fri Jan 17, 2020 11:32 am

Can you have a negative pH? If so, what does that mean conceptually? Does a concentration of 1 mean that 100% of the solution is H30+? And if that is true then how does that make sense?

You can receive a negative pH if the molarity of the strong acid is large enough. However, I do not know the mathematical reasons as to why this occurs.

Superacids can have negative pH if the concentration of H3O+ is greater than 1, because if you take the negative log of a value greater than 1 you get a negative value
