WebbpH is a determined value based on a defined scale, similar to temperature. This means that pH of water is not a physical parameter that can be measured as a concentration or in a quantity. Instead, it is a figure between 0 and 14 defining how acidic or basic a body of water is along a logarithmic scale ¹. WebbSo if you did wonder why pH is measured only on a scale of 0 to 14 and not negative values or in 100s, you can get the answer to that question here.
