Reason for Application

Indonesia national. I graduated in July 2012, from Bandung Institute of Technology, Indonesia and hold a Bachelor degree in Chemistry. I choosed to focus on applied electrochemistry because i have many curiosities to study this field. While studying electrochemistry, i fell very interisting to observe theory and application about electrochemistry. During my bachelor study, i have been proving myself to retain the top position of student in the class so that i have successfully achieved the scholarship (2009-2012)...

Experiments to Calculate the Value of the Formation Constant of Tetraamminecopper

Grace H. Kim Dec. 15, 2011 Abstract Two experiments were conducted to figure out the value of the formation constant of tetraamminecopper(II), Kf, with different methods and which experimental method produces more accurate result. One was electrochemistry using a Daniel cell and the other one was spectrometry by estimating concentration of complex solution using a calibration curve. The formation constant of cupric ammine complex Cu(NH3)42+, Kf, came out with 1.93x10^15 using electrochemical cell...

Determining the Standard Reduction Potentials of Different Electrochemical Half-Cells

reaction quotient. Other than human error, these factors affect the calculated values for Ecell. INTRODUCTION Electrochemistry is the branch of chemistry that deals with the relationship of electricity and chemical reactions. Batteries, control of corrosion, metallurgy and electrolysis are some of the many applications of electrochemistry in everyday life. Electrochemistry always involves an oxidation-reduction process, wherein electrons are transferred from one substance to the other. This...

Synthesis and Chemistry of K2S2O8

Quantity of electricity refers to the quantity of electrical charge, typically measured in coulombs. The actual yields are frequently less than this number of grams because of side reactions, and so percentage yields are usually evaluated. In electrochemistry, percentage yield is called current efficiency. Percentage yield = current efficiency = (actual yield/theoretical yield) x 100 The peroxodisulfate anion, S2O82-, can serve as a counterion to form stable and highly insoluble salt, observed...
