The paper chromatography can be calculate Rf Rf value (Rate of flow) is a substance-specific value depends on the type of solvent and adsorption of Rf values, so tell me each type of substance say the type of solvent. Rf can be calculated from the formula
.Up Rf = distance additives/mobile distance mobile solvent substances different types will have different Rf values. Therefore, we can use the Rf values to be used in analyzing the type of substance. That is, Rf because solvent will be moving faster than the substance that will split up the Rf is always less than one 1 always use solvent and adsorption of the same type, the same Rf value. It is assumed that these compounds may be of the same type to compounds.
