Ph meter structure
Webb10 feb. 2024 · There are two electrodes in a pH meter, and both are submerged into the solution. One of the electrodes is a glass electrode probe that emits a small voltage and measures the quantity of hydrogen ions attracted to it. The reference probe is electrically neutral. The charge difference between the two probes displays as a pH measurement … WebbThe pH scale, from 0 to 14, is a measure of the acidity or alkalinity of a solution, and can be measured using universal indicator or a pH probe. A solution with pH 7 is neutral. …
