Can a mixture of chloroform(b.pt.`61^@C`)andcarbontetrachloride(b.pt.`77^@C`)be satisfactorily separated by the process you use for separating the various fractions of petroleum?

State briefly how would you separate or name the process use to separate : Alcohol from a mixture of alcohol and water.

Give first the step you will use to separate the variable and then solve the equation: b/2 = 6

State briefly how would you separate or name the process use to separate : Sulphur from a mixture of carbon particles and powdered roll sulphur.

Which of the following statement is/are correct about acetone and trichloromethane mixture? a) Mixtures of acetone and trichloromethane show positive deviation from Raoult's law b) The forces of attaction acting between molecules of acetone and trichoromethene in a mixture are stronger then those acting between the molecules in pure acetone c) Pure acetone can be obtained by the careful fractional distillation of any mixture of acetone and trichloromethane d) When acetone and trichoromethane are mixed, the enthapy change negative

Read the following passage and answer the questions. Ultrafiltration is the process of separating the colloidal particles from the solvent and soluble solutes present in the colloidal solution by specially prepared filters, which are permeable to all substances except the colloidal particles. Colloidal particles can pass through ordinary filter paper because the pores are too large. However, the pores of filter paper can be reduced in size by impregnating with collodion solution to stop the flow of colloidal particles. The usual collodion is a 4% solution of nitrocellulose in a mixture of alcohol and ether. An ultra-filter paper may be prepared by soaking the filter paper in a collodion solution, hardening by formaldehyde and then finally drying it. Thus, by using ultra-filter paper, the colloidal particles are separated from rest of the materials. Ultrafiltration is a slow process. To speed up the process, pressure or suction is applied. The colloidal particles left on the ultra-filter paper are then stirred with fresh dispersion medium (solvent) to get a pure colloidal solution. What is collodion ?
