An aqueous solution of 0.40 M silver nitrate, AgNO3, and 0.40 M iron(II) nitrate, Fe(NO3)2, is allowed to reach equilibrium according to the following chemical reaction. Ag+(aq) + Fe2+(aq) equilibrium reaction arrow Fe3+(aq) + Ag(s) If the equilibrium constant, Kc, for the reaction is 1.7 at a certain temperature, determine the equilibrium concentrations of Ag+, Fe2+, and Fe3+.
ID Problems 46) A piece of silver (Ag) metal weighing 194.3 g is placed in a graduated cylinder containing 242.0 mL of water. The volume of water now reads 260.5 mL. From these data calculate the density of silver 47) The following procedure was used to determine the volume of a flask. The flask was weighed dry and then filled with water. If the masses of the empty flask and filled flask were 56.12 g and 87.39 g, respectively, and...
Sterling silver is a solid solution of silver and copper. If a piece of a sterling silver necklace has a mass of 160.0 g and a volume of 15.42 mL, calculate the mass percent of copper in the piece of necklace. Assume that the volume of silver present plus the volume of copper present equals the total volume. (Density of Cu = 8.96 g/cm^3: density of Ag = 10.5 g/cm.) mass percent of copper = mass of copper/total mass times...
? Fe (ag) reacts with MnO Caq) ion in acidic solution to yield Fe (ag) ions and Mn'(a) ions. 5 Fe"(aq) + Mno.(aq) + 8H' ? 5 Fe"(aq) + Mn"(aq) + 4H20 A sample of melanterite, FeSO, 7H,O, was analyzed for purity using this reaction by titration of an aqueous solution of the sample. One such sample required 56.15 mL of 0.01301 M permanganate solution to completely titrate all the iron in the sample by the reaction shown above. How...
