What is Origin of the pH Symbol Explained about?

The symbol pH originated from work by Danish biochemist Søren Peter Lauritz Sørensen in 1909. Sørensen was investigating the use of a hydrogen electrode to measure acidity in solutions. He found it convenient to express hydrogen ion concentrations as the negative logarithm of the concentration. Sørensen used the term "pH" to represent the numerical value of this exponent.
