pH value 1 (SB-43)

Calculate the pH of a 3 molar solution of hydrochloric acid

---

The pH value is the negative logarithm of the concentration of H₃O⁺ Particles in a solution. The concentration must be within the range of 1 mol/l to 10^-14 mol/l In this way, a possible pH value of pH = -log 1 = 0 up to pH = -log 10^-14 = 14.
The answer (to the question) is thus: it cannot be said, since the concentration is greater than the concentration of as 1 mol is per litre.
