Ph is negative logarithm of
WebbThe pH is defined as the negative log 10 of the hydrogen ion concentration expressed in mol/L. A negative logarithmic scale is used because the numbers are all less than 1, and vary over a wide range. … High pH numbers, e.g. pH 7.8, represent lower hydrogen ion concentrations, i.e. alkaline solutions. Is pH a positive or negative logarithm? Webb24 dec. 2024 · The pH scale is calculated by a negative logarithm. A negative logarithm of base b is simply how many times a number must be divided by b to reach 1. [3] The pH equation can be seen as follows: pH = -log 10 [H 3 O + ]. [4] The equation can sometimes be seen as pH = -log 10 [H + ].
