As anticipated in Poutnik's comment above is difficult to reliably measure a p H of very acidic solution but the p H scale is indeed open, and negative p H are a real thing. It is easy and more meaningful to state a very high concentration or activity rather than reporting inaccurate p H.

Because the constant of water, K w is \(1.0 \times 10^{-14}\) (at 25° C), the \(pK_w\) is 14, the constant of water determines the range of the pH scale. To understand what the pK w is, it is important to understand first what the "p" means in pOH and pH. The addition of the "p" reflects the negative of the logarithm, \(-\log\). Therefore, the pH is the …
