Tlc stands for a couple things Response details:1) factor that affects the rf value of tlc is the polarity of the solvent. It allows for the direct visual comparison between the sample and a known standard, helping to identify.
It doesn't depends upon the tlc plates. The order of increasing rf values in tlc is benzil, methanol anthracene and tryphenyl As it depends upon the solvents in which these compounds migrate.
Why is sand added when performing thin layer chromatography Sand is added when performing thin layer chromatography (tlc) to create a stable and uniform support for the tlc plate.
