Extraction Of Sodiumextraction Of Sodium By Downs Method On industrial scale sodium metal is extracted by "downs process" principle downs process is based on the electrolysis of fused nacl construction of downs cell downs cell consists of a rectangular container of steel inside of the tank is lined with The Basics Of Dna Extraction Alaska Bioprep Virtual Textbook The dna extraction process frees dna from the cell and then separates it from cellular fluid and proteins so you are left with pure dna the three basic steps of dna extraction are 1 lysis 2 precipitation and 3 purification precipitation separates dna from this cellular debris first na ions sodium neutralize the negative charges Chemguide Sodium Occurrence Extraction From Downs Molten sodium hydroxide caustic soda naoh is electrolyzed using an iron cathode and nickel anode a nickel wire gauze cylinder prevents the electrodes from touching each other on passing electric current through the melt sodium is liberated at the cathode and oxygen at the anode Manufacture Of Sodiumna By Downs Process Grade 11 Principle downs cell is a special type of cell that is made for extraction of sodium during the extraction of sodium metal following difficulties are seen a sodium ores like nacl na 2 co 3 are very stable b the chemical reduction of those sodium salts is not possible since sodium itself is Extraction Of Sodium Mastering Chemistry Help Extraction of sodium as sodium is a highly electro positive metal it cannot be prepared by the usual methods of reduction the metal is extracted by the electrolysis of a molten mixture of nacl cacl 2 and kf in a downs cell at 600 degree celsius the cell has a graphite anode and a circular iron cathode both covered and with proper outlets
