I. Introduction
Power of Hydrogen or more commonly known as pH is a numeric scale of 0 to 14 which
is used to classify an aqueous solution whether the solution is an acid or a base(Bates, 1973).
The Danish scientist who introduced the concept of pH is Søren Peder Lauritz Sørensen at the
Carlsberg Laboratory in 1909(Sorensen, 1909). The pH is approximated by the formula,
negative logarithm base 10 of the molar concentration of hydrogen ions(Equation 1.1)(Rodwell,
2015). It is accepted that the range 0 to 14 pH is the limits of the numeric scale. At around pH 7
it is referred to as neutral, pH above 7 is called basic due to the ionized hydroxide, and finally,
pH below 7 is acidic due to the ionized hydrogen. (Parsons and Schapiro, 1975)
