pHindikatorpapper
pHindikatorpapper, often referred to as pH paper, is a strip of paper that has been treated with a pH indicator. These indicators are compounds that change color in a predictable way as the acidity or alkalinity of a solution changes. When a strip of pH paper is dipped into a liquid, the indicator on the paper reacts with the hydrogen ions in the solution, causing a color change. The color observed on the paper is then compared to a color chart that is usually provided with the paper. This chart shows the corresponding pH values for each color.
The purpose of pH indicator paper is to provide a quick and simple method for estimating the
While pH indicator paper is convenient and inexpensive, it is important to note that it provides an
