The components of universal indicator solution can best be separated by
Answer Details
Universal indicator solution is a mixture of different indicators that changes color over a range of pH values. The best method to separate the components of universal indicator solution is chromatography.
Chromatography is a method used to separate different components of a mixture based on their physical and chemical properties. In this case, the components of universal indicator solution can be separated based on their different solubility and adsorption properties. A small amount of the solution is placed on a chromatography paper and allowed to separate through the paper by capillary action. The different components of the mixture will travel at different rates based on their solubility in the solvent and their interaction with the paper. As a result, the different components can be separated and identified by their distinct color changes as they travel through the paper.
Filtration, evaporation, crystallization, and fractional distillation are all separation methods that are based on the physical properties of the components of a mixture, such as their boiling points or solubility in a particular solvent. These methods are not suitable for separating the components of universal indicator solution, which are all indicators with similar physical properties.
