Question

A solution contains 0 05 M Au^+, 0 05 MCu^+, and 0.05 M Ag^+ ions. When solid NaCl is added to the solution, what is the order in which the chloride salts will begin to precipitate? Which of the following species is the strongest oxidizing agent? Ag^+ Fe^2+ Br_2 Li Br^- Which of the following statements about the operation of a standard galvanic cell, Al [AI^3+ (1 M)] Pb^2+(1 M)/Pb, is false The chromium electrode is oxidized The [Pb^2+] decreases The mass of the lead electrode decreases The [AI^3+] increases The salt bridge maintains charge neutrality Complete and balance the following equation in acidic solution (H^+ or H_2O may he added as necessary). What is the coefficient of water? BrO_3^- + Cl^- rightarrow Cl_2 + BrO_2 Suppose we let the reaction below come to equilibrium. Then we decrease the total pressure, by increasing the volume of the container. What will be the effect on the net amount of SO_3(g) present? The question cannot be answered without knowing the value of K 5. It increases The question cannot be answered without knowing the value of Delta H^0. It decreases It does not change.

Explanation / Answer

Solution:

Answer for the fie st question is E.

AuCl > AgCl > CuCl as Ksp for the AuCl < AgCl < CuCl
