Alternatively, absorbance spectroscopy may be used with a pH indicator to calculate the pH usingBeer's law. Spectroscopic pH measurements using a single acid-base indicator are accurate to within one pKa value. Combining two or more indicators increases the accuracy of the measurement. Indicators ar...
Mathematical definition of pH is a little less intuitive but more useful in general. It states that the pH equals the negative logarithmic value of the concentration of hydrogen ion (H+) pH = -log [H+] A water source ‘s pH value is a function of its acidity, or alkalinity. The pH ...
