pH out of the 0-14 scale

Postby josmit_1D » Sat Nov 30, 2019 5:25 pm

what does it mean if the calculated pH is negative or above 14?

If it is negative then that substance is a super strong acid. If it is above 14 then that substance is a super strong base.

pH is a measure of the concentration of H+ ions, or more accurately, H3O+.

It's measured using the -log[H+].

The normal pH range is 1 - 14, but if the H+ concentration is higher (super acid) or lower (super base), it'll be outside that range.
