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 method
