WebSep 1, 2024 · The ion exchange generates a voltage, which is measured by a pH meter that converts the voltage to a readable pH value. It is a water quality sensor that measures the pH level of a liquid. pH (hydrogen potential) measures the interaction between hydrogen and hydroxide ions in a water-based solution. In acid-base titrations, an unfitting pH indicator may induce a color change in the indicator-containing solution before or after the actual equivalence point. As a result, different equivalence points for a solution can be concluded based on the pH indicator used. This is because the slightest color change of the indicator-containing solution suggests the equivalence point has been reached. Therefore, the most suitable pH indicator has an effective pH range, where the ch…
