Question- We are interested in testing the method used by Boeing for removing Cu2+ from solution using scrap metal. In this case solid aluminum scrap.
G^0 Cu2 + (aq) = 65.5 kJ/mole
G^0 Al3 + (aq) =-489.4 kJ/mole
(a) Write a balanced equation for the reaction and calculate the deltaGr for the reaction of Cu2+ and Al metal.
(b) Calculate the Keq for the above reaction and calculate the Er or Pe of a sample of the above water given an initial Cu2+ concentration of 1.2
x 10^-3 M and an excess of solid Al
Any expert will able to provide correct answer for the above question.
