PPT-Electrolysis & Understanding

Electrolytic Cells When a nonspontaneous redox reaction is made to occur by putting electrical energy into the system The battery energy source acts as a pump pushing electrons into the cathode and removing electrons from the anode. 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. Mr. Chapman. Electrolysis. Think of . electrolysis. . and . electrolytic cells. as the . opposite . of . electrochemical cells. .. In . electrochemical cells. , a spontaneous REDOX reaction . is used to create . Medical Electrolysis. What is Electrolysis?. It’s a method of permanent hair removal. It’s the only method of hair removal that’s FDA approved. It can be done on any area of the body. As long as we can see the hair, we can remove it.. Electrolytic Cells. REVERSE spontaneous reactions through the input of . electricity .
