Unformatted text preview: Lab Experiment #11 Electroplating and the Measurement of Avogadros Number Ryan Henry Section 523 Lab Partner: Charlotte McCoy Summary : This experiment is meant to illustrate the effects of solution concentration and current on the physical characteristics of tin and copper. By measuring the electric current that flows through the solution over a period of given amount of time, we were able to find an experimental value for Avogadros number. Electrolysis is the process in which electrical energy is used in order to force a chemical reaction to occur. In this particular lab the reaction is the deposition of a tin film onto copper metal; a process known as electroplating. In this lab, the metals are cleaned in an acidic solution to avoid any error. After the cleaning, both of the metals were placed in the tin solution and the current turned up to about .3 amps. The current is allowed to flow for 5-10 minutes. I observed the physical characteristics of the metal as time went on and I flow for 5-10 minutes....
