Which statement in the following choice ate true? Select all that apply. Chromatography is a technique in which a mixture of different substances are separated based on how easily they are dragged on a solid substance called stationary phase on which they are deposited. They are dragged by a substance called mobile phase. Chromatography is a technique in which a mixture of different substances are separated based on how easily they are dragged on a medium called mobile phase on which they are deposited. They are dragged by a medium called stationary phase. The mixture of substances adheres to, or in other words is adsorbed to the stationary phase. The strength of the adsorption follows the principle according to which "like dissolves like", meaning that high polarity stationary phase adsorbs a lowly polar substance more strongly than a highly polar one. The mixture of substances adheres to, or in other words is adsorbed to the stationary phase. The strength of the adsorption follows the principle according to which "like dissolves like", meaning that high polarity stationary phase adsorbs a highly polar substance more strongly than a lowly polar one.

The strength of the adsorption follows the principle according to which "like dissolves like", meaning that high polarity stationary phase adsorbs a highly polar substance more strongly than a lowly polar one. Another medium, called the mobile phase, either in the liquid or in the gas state, is circulated over the stationary phase. As the mobile phase passes over the stationary phase, it competes for adsorption with the substances which are already adsorbed, and thereby displaces and drags them over the stationary phase from one site to the next site. Another medium, called the mobile phase, either in the liquid or in the gas state, is circulated over the stationary phase. As the mobile phase passes over the stationary phase, it competes for adsorption on the stationary phase with the substances which are already adsorbed, and thereby binds them even more strongly on the stationary phase.
