Explain what reaction occurs when sodium hydroxide is added to the stearic acid in cyclohexane and water? Define how does this change the solubility of cyclohexane in water? Does HCL reverse this reaction as well as if so why? Does sodium chloride have the same kind of behavior as stearic acid or is it different? Define why these two solutes are the same or different.
A copper, Cu(s), electrode is immersed in a solution that is 1.00 M in ammonia, NH3, and 1.00 M in tetraamminecopper(II), [Cu(NH3)4]^{2+}. If a standard hydrogen electrode is used as the cathode, the cell potential, Ecell, is found to be 0.081 V a..
