Answer:
b similar solubility in water
Explanation:
Chromatography is a quantitative technique, its general purpose being two uses, substance identification and separation-purification of mixtures. Using properties like solubility, size and mass. An important principle of this technique is that similar solubility in water must be present between the elements.
For the mixture separation process, the mixture goes through two phases, one stationary (fixed, being a porous material as a filter) and another mobile (such as a liquid or a gas, which helps in the separation of the mixture). constituents of these mixtures interact with the phases through intermolecular and ionic forces, making the separation. The mixture may be separated into several parts or further purified by eliminating undesirable substances.
