How does a ph meter work edu
WebThe pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution. The letters pH stand for "power of hydrogen" and the numerical value is defined as the negative base 10 logarithm of the molar concentration of hydrogen ions. pH = -log10[H+] WebMar 1, 2024 · A pH meter is an example of an ion-selective electrode. The pH meter has a thin-walled glass membrane that measures the [H+] difference between a standard known [H+] concentration inside the pH meter and that of solution the meter is placed in. This [H+] difference is used to find the pH of the solution.
