During an experiment, you will be required to prepare 100 mL of a 1.0 M solution of NaNO3. Calculate the mass of NaNO3 (to the nearest tenth of a gram) that will be required.
The initial concentrations of Pb2+ and Ag+ are 0.05M and for Cl- 1.5M. Assume all the present Pb2+ and Ag+ precipitate out of solution. Use the remaining Cl- concentration and the Ksp and Kf reactions for AgCl and AgCl2-, respectively, to determin..
the standard reduction potential for the cu2+/cu redox couple is +.34V; that for h2o/H2, OH- at a ph of 7 is -.41V. For the electrolysis of a neutral 1.0M CuSo4 solution, write the equation for the half reaction occuring at the cathode at standard..
