![]() So, the mixture of liquids ‘A’ and ‘B’ can be separated by fractional distillation. We can separate two miscible liquids by fractional distillation, if both the liquids have difference in their boiling points. Which separation technique will you apply to separate the mixture of ‘A’ and ‘B’ if the difference in their boiling points is 27☌? Two liquids ‘A’ and ‘B’ are miscible with each other at room temperature. In what respect does a true solution differ from a colloidal solution?Ī true solution is homogeneous whereas a colloidal solution is heterogeneous. The two components of a colloidal solution are dispersed phase and dispersing medium. What are the two components of a colloidal solution? It is defined as the mass in grams of the solute present in one hundred grams of a solution. Iodine is the solute and alcohol is the solvent. Identify solute and solvent in ‘tincture of iodine’. It is a pure substance because chemical composition of sugar crystals is same irrespective of its source.īased on which factor a solution is said to be diluted, concentrated or saturated?Ī solution is said to be diluted, concentrated or saturated on the basis of the amount of solute dissolved in the solution. Will it be a pure substance or a mixture? Give reasons for the same. Sucrose (sugar) crystals obtained from sugarcane and beetroot are mixed together. How can you change a saturated solution to an unsaturated solution without adding any more solvent to it?īy heating the saturated solution, it becomes unsaturated.
