1. Balance the following redox reactions in acidic or basic solution a. NH3(g) + O2(g)= NO(g) + H20(O [acidic] b. Pb02 + Cl¯= Clo- + Pb(OH)3 [basic] c. Ag2S + CN- + 02=S+ Ag(CN)2" + H20(!) [basic] When metal A is placed in a solution of a salt of metal B, the surface of metal A changes color. When metal B is placed in acid solution, gas bubbles form on the surface of the metal. When metal A is placed in a solution of salt and metal C, no change is observed in the solution or on the metal A surface. 2. a. For each observation stated, what conclusions can you draw? b. From these observations rank metals A, B and C in order of likelihood to oxidize and make a standard reduction potential table for the half-reactions in this problem. c. Will metal C cause formation of H2 when placed in acid solution?
