PPT-ELECTROLYSIS

The purpose of electrolysis is to split up ionic compounds using electricity to produce useful products Electrolysis is used a lot in industry and is a multibillion pound industry It is used to produce all of the Copper Aluminium Chlorine and Caustic Soda sodium hydroxide that we use today as well as to produce gold and silver plated jewellery and chromeplated taps and bicycle parts. The electrolysis of aqueous solutions. Aqueous. solutions are solutions in . water. .. Water is a very weak electrolyte. It ionises very slightly to give hydrogen ions and hydroxide ions.. H. 2. O. (l). LQ: What happens at the electrodes?. Learning outcomes. I can describe electrolysis as the decomposition of an electrolyte with an electric current – Grade B. I can describe the changes at the electrodes during electrolysis – Grade A. Putting electrical energy in to force the . nonspontaneous. change. electrolysis. Opposite process to electrochemical (voltaic) cells. Electrical energy is put into the reaction. The . nonspontaneous. Electrolytic Cells. :.

Hair is an appendage of the skin that is slender, thread like out-growth of the skin and scalp.. Terminal hairs are the heavier concentration of hair found on the head, under the arms, on and around the genitals and on the arms and legs.. What is the positive electrode called?. What is the negative electrode called?. Label a diagram showing the electrolysis of molten copper bromide (CuBr. 2. ). ELECTROLYTIC PROCESSES. What does OILRIG stand for?. Mogens B. Mogensen .
