Q. How to Prepare Chlorine in Laboratory?
Chlorine is prepared by oxidation of hydrochloric acid with potassium permanganate:
2KMnO4 + 16HCl -> 2KCl + 2MnCl2 + 8H2O + 5Cl2
The gas is bubbled through water to remove any unreacted hydrochloric acid and dried by bubbling through sulfuric acid. Being denser than air, it can be collected by downward delivery.
Osmotic pressure: Osmosis process is the movement of a solvent from a solution of lower solute concentration (higher solvent concentration) to one of the higher solute concentr
