in identification of phenol with fecl3 if we add an acid (e.gCl) color of complex will disappear >why?
FeCl3 is commonly used in the identification of phenol because it forms a colored complex with phenol, allowing for easy visual detection of its presence.
Yes, FeCl3 can also be used to identify other compounds such as carboxylic acids, alcohols, and amines. However, the color change observed may vary depending on the compound.
The presence of phenol is indicated by a purple or violet color change when FeCl3 is added. This is due to the formation of a complex between FeCl3 and the hydroxyl group on phenol.
Yes, there are some limitations to this method. Other compounds with similar functional groups, such as cresols and anilines, may also give a positive reaction with FeCl3, leading to potential false positives.
The concentration of FeCl3 used can vary depending on the sensitivity and specificity desired. A commonly used concentration is a 1% solution, but it is important to note that the intensity of the color change may also be affected by the concentration of the compound being tested.
