Observation Different components (red and green ink) of ink get separated. Fig. Separation of dyes in black ink using chromatography This process of separation of components of a mixture is known as chromatography. Kroma in Greek means colour. This technique was first used for separation of colours, so this name was given.

Homogeneous and Heterogeneous Mixture

Summary A mixture is a physical blend of two or more components, each of which retains its own identity and properties in the mixture. A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. All solutions would be considered homogeneous. A heterogeneous mixture is a mixture in which the composition is not uniform throughout the

Selective separation of galena and sphalerite from pyrite

A mixture design is a special type of experimental design in which the factors are the ingredients or components of a mixture, and the response is a function of the proportions of each ingredient. In many mixture experiments there are constraints on the component proportions. The general form of the constrained mixture problem is x1 + x2 +⋯+ xq=1
