Answer to Question #56828 in Other Chemistry for Aryan Sahu
you are given a powdered mixture of sulphur,potassium nitrate and carbon.state briefly how could you separate and collect each constituent in solid or powdered form?
1. Dissolve the mixture in enough quantity of water – KNO3 will dissolve. 2. Filter the solution and evaporate filtrate carefully – you’ll get KNO3 solid. 3. Heat gentle dried mixture of C & S. Melting point of sulfur is about 1130C – you will separate sulfur in liquid state (cool it and get solid S). Carbon stays.
