Can a ph value be negative

WebThe normal range of pH values are 0 to 14, which have corresponding [H 3 _3 3 O + ^+ +] values of 1 M to 1.0 × \times × 10 − 14 ^{-14} − 14 M. For a pH value to be negative, its [H 3 _3 3 O + ^+ +] should be greater than 1 M. In this case, a pH value can be negative since strong acids with concentrations greater than 1 M do exist (e.g. 2 ... WebMar 2, 2024 · Before taking a pH measurement, the meter must be "calibrated." The probe is immersed in a solution that has a known pH, such as pure water with a neutral pH of 7.0. The knobs on the box are used to adjust the displayed pH value to the known pH of the solution, thus calibrating the meter. Taking pH at home or school
