indikatorspapper

Indikatorpapper, often referred to as pH-papper or lackmuspapper, are strips of paper impregnated with a chemical indicator. These indicators undergo a color change when exposed to solutions of varying acidity or alkalinity, commonly measured by the pH scale. The specific indicator used determines the range of pH values the paper can detect and the corresponding colors. For instance, universal indicator papers contain a mixture of indicators, allowing them to display a spectrum of colors across a wide pH range, typically from 1 to 14. Simple litmus paper, on the other hand, usually shows red in acidic solutions and blue in alkaline solutions. To use indikatorpapper, a small portion of the paper is dipped into the solution being tested. The resulting color is then compared to a color chart provided with the paper, which indicates the approximate pH value. These papers are widely used in laboratories, educational settings, and for simple household tests due to their ease of use and affordability. They are valuable tools for quickly assessing the acidity or alkalinity of substances without the need for more complex electronic pH meters.
