pH can be in the range of small negative values up to greater than 15.
The definition allows this.
If the molarity of a strong acid is 1.00 M then the [H+] is 1.00 M.
pH will be -log 1.00. That gives a pH of 0.00.
If we have a 2.00 M strong acid giving a [H+] of 2.00 M
pH will be -0.30.
Full strength sulphuric acid has a molarity of 18 M. You do the math.
If we have 2.00M NaOH that produces a [OH-] of 2.00M
pH will be 14 - pOH or 14 - (-0.30) = 14 + 0.30 = 14.30.
Most pH meters have trouble with acids or bases that are highly concentrated and usually read from 0.00 to 14.00. That does not mean the pH isn’t as calculated, it is just the limitation of the measuring device.
I hope it help you...

Hey...!!!! :))
____________
____________
pH is zero if the hydrogen ion.
Reason:-
because hydrogen bion concentration is 1 mole/litre at a temperature of 25 deg C.
The issue is still the subject of public misunderstanding. The head of a water company here in the UK was being challenged about acid pollution. In his press release he said "I can assure you that we are doing all we can to get the pH of the water supply back down to zero".
