Chromatography Questions & Answers

Most chemists and many other scientists must routinely separate mixtures and identify their components. The ability to qualitatively identify the substances found in a sample can be critical. For example, an environmental chemist investigating samples of polluted ground water will want to know which toxic ions might be present in a sample.

Chromatography Viva Questions With Answers

Explanation: Chromatography is a physical method that is used to separate complex mixtures. The mixture of different components is flushed through the system at different rates. In which type of chromatography, the stationary phase held in a narrow tube and the mobile phase is forced through it under pressure? Explanation: In Column chromatography, the stationary phase held in a narrow tube and the mobile phase is forced through it under pressure. It is carried out in a long glass column having a stop-cock near the bottom.
