What are the methods used to detect colourless spots in TLC
Accepted Answer
There are several methods used to detect colourless spots in TLC. One common method is to use a UV lamp. Colourless spots will often absorb UV light and appear as dark spots on the TLC plate. Another method is to use a chemical spray reagent. The spray reagent will react with the compound in the spot and produce a coloured product. This will make the spot visible on the TLC plate.
