본문 1. Subject : Electrolysis and Electoplating 2. Date : 2010. 5. 17 3. Theory Electrolysis : Electrolyte is disintegrated as constituent causing chemical change by current. - Construction : Soak white gold or carbon electrode in electrolyte solution and connect in power supply and leading wire. - If flow direct current in electrolyte aqueous solution or melt, cationic is reduced at cathode and anion is oxidized at anode. Cathode : cationic + e- → simple substance Anode : anion → simple substance + e- Electrolytic cell : a type of chemical cell in which the flow of electric energy from an external source causes a redox reaction to occur. Faradays Law of Electrolysis - Rule that explain relation between mass of created material and spilling quantity of electric charge when electrolysis occurs. 1)First law : Creation and exhausted amount of substance in electrolysis are proportioned quantity of electric 2)Second law : Amount of substance educed by fixed quantity of electric charge is proportioned atomic weight / charge number of ion. m = ( Q over F )( M over z ) m : the mass of the substance liberated at an electrode Q : the total electric charge passed through the substance F : 96,485 C mol-1 is the Faraday constant M : the molar mass of the substance z : the valency number of ions of the substance (electrons transferred per ion) 1F = Quantity of electric charge of electron 1mol = Quantity of electric charge of 1 electrons × Avogadros number = (1.60×10-19C)×(6.02×1023)≒96485C/mol - When flowed quantity of electric charge of 1F, material as move electron 1 mole is educed. Electroplating : Method surface of object to other metallic plated with thin film by electrolysis reaction 4. Reagents (1)Copper sulfate solution a)Chemical formula : CuO4S, CuSO4 하고 싶은 말 좀 더 업그레이드하여 자료를 보완하여, 과제물을 꼼꼼하게 정성을 들어 작성했습니다. 위 자료 요약정리 잘되어 있으니 잘 참고하시어 학업에 나날이 발전이 있기를 기원합니다 ^^ 구입자 분의 앞날에 항상 무궁한 발전과 행복과 행운이 깃들기를 홧팅 키워드 결과, 도금예비, 레포트, 실험레포트, 도금, 실험레
