When an acid is dissolved in water, by releasing protons into the solution, it lowers the pH.
What is pH?
The letters pH stand for the potential of hydrogen since pH is essentially a measurement of the number of hydrogen ions (i.e. protons) in a substance. The pH scale was created in 1923 by scientist Peter Lauritz Srensen. (1868-1969).
The pH of a solution is a key marker of its chemical makeup. The pH can have an impact on the biological processes that take place, the behavior of bacteria, and the behavior of chemicals.
