<h2>Answer with Explanation </h2>
Chromatography is utilized to isolate blends of substances into their segments. All types of chromatography chip away at a similar guideline. They all have a stationary stage (a strong, or a fluid bolstered on a strong) and a portable stage (a fluid or a gas). A paper chromatogram can likewise be utilized to recognize substances by contrasting them and known substances. Two substances are probably going to be the equivalent in the event that:
- they deliver a similar number of spots and these match in shading.
The spots venture to every part of a similar separation up the paper (have a similar R f esteem). Rƒ esteem, solutes, and solvents. The maintenance factor (Rƒ) might be characterized as the proportion of the separation ventured out by the solute to the separation gone by the dissolvable. It is utilized in chromatography to measure the measure of the hindrance of an example in a stationary stage in respect to a portable stage.
