Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Chromatography is based on the difference in solubility of the individual components of a mixture. As a result, the components that are more soluble in the solvent (mobile phase) will travel a farther distance on the stationary phase than the others. [2 marks]
