pH scale

Postby Rohan Kubba Dis 4B » Fri Nov 29, 2019 3:10 pm

I understand that pH is a concentration, mostly of Hydronium ions (sometimes Hydroxide), however, it goes from 1 to 14. I know that the 14 is equal to 1.0 x 10^-14M (basic), however, can the basic scale extend beyond 14?

It can, but these substances are rare and not really relevant if you're not a chemist for example. Any pH above 9 or 10 is already considered extreme

It could but I think all that we should know will stay in between 1 and 14.

Most of the substances that we will work with, if not all, will have pH values between 0 and 14 corresponding to Hydronium ion concentrations that range from 1 * 100 M*L-1 to 1* 10-14 M*L-1

I doubt that anything beyond the 1-14 scale will be tested on, so I wouldn't worry about that.
