Indicating Solution pH 3.8 - 5.4 (Bromocresol Green)
The indicator solution with bromocresol green is widely used in chemical analysis and teaching, especially in the titration of acids and bases. The specific pH range of 3.8 to 5.4 is relevant for numerous biological, chemical and medical applications.
The solution is particularly suitable for use in areas where accurate determination of pH values in an acidic environment is required. Due to the characteristic color change of bromocresol green at different pH values, the solution allows direct visualization of pH changes.
Bromocresol green, the active component in the solution, functions as a weak acid that absorbs or releases protons as pH changes. This process results in a visible color change that indicates the pH of the solution.
The operation of the indicator solution is based on the color change of bromocresol green. In acidic environments, bromocresol green appears yellow, while at pH levels above 5.4 it appears blue. This distinct and easily recognizable color change enables fast and accurate determination of pH in a variety of applications.
