In other words, at a high concentration, e.g. 1 mol/L = 100, pH = 0 (ACIDIC) at a low concentration, e.g. 10-14 mol/L, pH = 14 (ALKALINE) Hence, different substances are objectively compared with each other, where pH 0 is extremely acidic, pH 14 extremely alkaline, and pH 7 neutral. In the last few years the measuring of pH has gained in. proportional to the pH of the liquid. The pH meter measures the voltage and uses a temperature-dependent fac-tor to convert the voltage to pH. Because the cell has high internal resistance, the pH meter must have a very high input impedance. Figure 2-1 shows separate measuring and reference electrodes.

A pH meter  is an electronic device used for measuring the pH (acidity or alkalinity) of a liquid. A typical pH meter consists of a glass electrode connected to an electronic meter that measures and displays the pH reading. Shown in Figure 1 is the high precision pH meter Metrohm that uses in the Department of Chemistry and Department of. The pH scale is logarithmic so, for example, if sample A is 1 pH less than Sample B, this means that Sample A is 10 times more acidic then Sample B. A difference of 1 pH represents a ten-fold difference in acidity.
