Why decanting is not a good way of separation?

Decanting is not always an effective method of separation because it relies on the difference in density between liquids or solids, which may not be significant enough for clear separation. Additionally, decanting can leave behind impurities or small particles that remain suspended in the liquid. Furthermore, it is not suitable for separating homogeneous mixtures, where the components are uniformly distributed. Overall, while decanting can work for certain scenariOS, it is often less precise than other separation techniques like filtration or centrifugation.
