    Electrochemical Cells Lab Report AP Chemistry Block 1 Analysis: The purpose of Part 1 of this laboratory is to construct a table listing the reduction potentials of a series of metal ions in order of ease of reduction. The series of half-cells is constructed by placing a piece of metal into a 1.0 M solution of its ions for each metal in the series. The metals are Cu‚ Fe‚ Pb‚ Mg‚ Ag‚ and Zn. The half-cells are connected by a salt bridge constructed of a strip of filter paper soaked in a solution

    Title: Redox Reactions Research Question: Is it possible to determine if a redox reaction took place by using only the equation? Hypothesis: Yes‚ I believe it is possible to determine if this reaction took place by using the oxidation numbers in the equation. Variables: 1. I cleaned the reaction surface to limit contamination 2. I held the chemicals at approximately a 90 degree angle for consistency Introduction: Redox reactions occur when both oxidation and reduction take place. All atoms

    I https://www.oppapers.com/join.php#submit .       Experiments with Metals and Ions of Metals         Introduction Metals are similar in their physical properties in general‚ but they are not identical. Most of the metals are solids; few of them are liquids‚ such as mercury and cesium. Density of metals is not similar also. For example‚ sodium has density of 0.97g/cm3 while lead has density of 11.4g/cm3. Melting point of sodium is 98.0oC while for lead it is 327.6oC. Metals have the capability

    The purpose of this lab was to measure the reduction potentials of metals and to understand how a reduction-oxidation relationship works to produce spontaneity. Lastly‚ these results were used to determine the Faraday’s constant and Avogadro’s number by electrolysis‚ which is chemical decomposition produced by passing an electrical current through a solution with ions. The primary objective of part one of this experiment was to discover how the properties of an electrochemical cell works. An electrochemical

    1. Results Part 1: When samples of austenitic stainless steel are immersed in a sulphuric acid solution and are taken through a current‚ it may be observed that corrosion products are formed around the electrodes‚ to differing degrees. The reason for this is because when a uniform voltage is applied across the series of interconnected electrodes in the acid solution different potentials are obtained at each electrode and hence different electrochemical reactions take place. The products of these
