A solution contains one or more of the following ions: Ag+, Ca2+, and Fe2+. When sodium chloride is added to the solution, no precipitate forms. When sodium sulfate is added to the solution, a white precipitate forms. Then, the precipitate is filtered off and sodium carbonate is added to the remaining solution, and a precipitate forms. Which of the ions were present in the original solution? Write net ionic equations for the formation of each of the precipitates observed.

A certain half-reaction has a standard reduction potential E0red = +0.13V . An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell.Required:a. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have?b. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have?
