Qualitative pH papers without color chart are simple, completely impregnated indicator
papers. They indicate if the pH of a solution is above or below the transition point (color
change) and are useful to distinguish between acids and bases.
UNISOL indicator solutions are used for pH determination in pure water, in surface
waters and in very dilute acids or bases. An indicator solution is added to the sample
and the reaction color is compared with a color scale. Therefore, they allow the easy
and reliable pH determination in weakly buffered solutions.
