Solved: Three electrochemical cells were connected in
Chapter , Problem 127(choose chapter or problem)
Three electrochemical cells were connected in series so that the same quantity of electrical current passes through all three cells. In the first cell, 1.15 g of chromium metal was deposited from a chromium(III) nitrate solution. In the second cell, 3.15 g of osmium was deposited from a solution made of Osn_ and nitrate ions. What is the name of the salt? In the third cell, the electrical charge passed through a solution containing X2_ ions caused deposition of 2.11 g of metallic X. What is the electron configuration of X?
