RankGuru · Accepted Answer

The **Retardation Factor ($R_f$)** is a ratio used to identify substances in chromatography (TLC or Paper).
- **Calculation**: $R_f = \frac{	ext{Distance traveled by the substance from the base line}}{	ext{Distance traveled by the solvent front from the base line}}$
- **Properties**: 
- The $R_f$ value is always **between 0 and 1**.
- It is a characteristic constant for a particular compound in a specific solvent system and stationary phase, enabling qualitative identification.
