WebpH is a logarithmic scale. A solution that has a pH of 1.0 has 10 times the [H +] as a solution with a pH of 2.0, which in turn has 10 times the [H +] as a solution with a pH of 3.0 and so forth. Using the definition of pH, it is also possible to calculate [H +] (and [OH − ]) from pH and vice versa. The general formula for determining [H ... WebFeb 24, 2024 · The pH scale is a tool chemists have devised to measure how acidic (or alkaline, the opposite of "acidic") a solution is. It is used every day in countless applications, from checking whether the chlorine level in your hot tub is where it should be to allowing biochemists to figure out ideal conditions for reactions affected by acidity to occur.
