Explain preparation and properties of phosphorus trichloride
It may be prepared by the action of phosphorus on thionyl chloride.P4 + 8SOCl2 4OCl3 + 4SO2 + 2S2Cl2 Lab. Method: it is more conveniently prepared in the laboratory by heating white phosphorus in a current of dry chlorine when phosphorus trichloride distils over.P4 + 6Cl2 4PCl3Phosphorus is gently heated in a retort on a water bath and current dry chlorine is passed. Phosphorus trichloride distils over and is collected in a receiver cooled in freezing mixture.It is redistilled over white phosphorus to remove any phosphorus pentachloride present an impurity.Properties It is colourless fuming liquid. It reacts violently with water forming phosphorus acid.PCl3 + 3HOH H3PO3 + 3HCl It reacts with concentrated H2SO4 forming chlorosulphonic acid. Or, 2H2SO4 + PCl3 HSO3Cl + HPO3 + SO2 + HCl It reacts with organic compounds containing hydroxyl group. It directly combines with Cl2, O2 and S. this indicates that it is an unsaturated compound.PCl3 + Cl2 PCl52PCl3 + O2 2POCl3PCl3 + S PSCl3 It acts as a reducing agent.PCl3 + SO2Cl2 PCl5 + SO2PCL3 + SO3 POCL3 + SO23PCl3 + S2Cl2 PCL5 + 2PSCl3It reacts with finely divided metals when hot.12Ag + 4PCl3 12AgCl + P46Na + PCl3 3NaCl + Na2P

Describe some of the significance of the organic chemistry in brief?
The free energy of a component of a liquid solution is equal to its free energy in the equilibrium vapour.Partial molal free energies let us deal with the free energy of the components of a solution. We use these free energies, or simpler concentration ter
Select right answer of the question. A dry air is passed through the solution, containing the 10 gm of solute and 90 gm of water and then it pass through pure water. There is the depression in weight of solution wt by 2.5 gm and in weight of pure solvent by 0.05 gm. C
