Mind-Blowing Fact
Drunk Science.
In 1909, the pH scale was invented by scientist and skilled brewer Søren Sørensen while experimenting with beer. In the search for the perfect pint, he explored the enzymes made from proteins and quickly realized that hydrogen ion concentrations were important to how these enzymes performed their functions. He developed the pH scale as a way to keep track of these conditions in a solution. The H in pH means hydrogen. The p is unknown, as he never did say what it meant, but it is speculated that it means power. Thus, pH means "Power of Hydrogen".
