INDICATOR PAPER With colour scale pH2.0-4.5
pH indicator papers supplied in rolls are perfectly suited for longterm storage,
since they are protected against external influences, such as moisture, light, and ambient gases.
These pH indicator papers are manufactured by impregnating high-quality filter paper with indicator or mixed-indicator solutions.
Application
A universal indicator is a pH indicator made of a solution of several compounds that exhibits several smooth colour changes over a wide range pH values to indicate the acidity or alkalinity of solutions.
Dosage
The colour of an indicator alters when the acidity or the oxidizing strength of the solution, or the concentration of a certain chemical species, reaches a critical range of values.
