PPT-Electrolysis

Explain the process of electrolysis and its uses Electrolysis A process where electrical energy is transformed into chemical energy It is not spontaneous electrical energy must be supplied for a . Pg. 658 - 660. Let’s talk about the lab…. In lab the reactions were spontaneous!. The solutions were arranged so that the electrons would move through the wires. Voltaic cells involving spontaneous reactions are typically used to run motors and perform other useful work. 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. :. When a non-spontaneous . 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.. Medical Laser. What is Laser Hair Removal?. It’s a method of permanent hair reduction.. It can be done on any area of the body.. It works best on hair that is brown or black. . Electrolysis. is an option for white, gray, or very blond hair..

Electrolytic. Baseline (Flightpath D): State that aluminium can be extracted from aluminium oxide using electrolysis. Write a word equation to describe the electrolysis of aluminium oxide. .. Further (Flightpath C&B): Describe the electrolysis of aluminium oxide. Explain why electrolysis is an expensive metal extraction method and illustrate this with the extraction of aluminium.. C3 Review PowerPoint Presentation. Qualitative Analysis is where you find out what type of substance you have present.. Quantitative Analysis is when you deduce the amount of unknown sample you have.. Information and Uses. Unit 2 - Mission to Mars Connection. Hydrogen . Hydrogen does not exist by itself. in nature. Uses for hydrogen. Oxygen. Uses for Oxygen. Water (H. 2. O. ) . A water molecule is made up of one oxygen atom sharing electrons with two hydrogen atoms. . Electrolysis . Process by which an electric current is passed through a substance to cause a chemical change.. The chemical change is one in which the substance loses or gains an electron.. Electrolysis.
