1. Sodium citrate: 0.015 M. Calculate the mass of sodium citrate dihydrate, Na3C6H5O7(H2O)2, needed to prepare 50 mL of a 0.015 M sodium citrate solution. 2. Silver nitrate: 5.0 x 10-4 M. Calculate the volume of 0.20 M AgNO3 solution needed to prepare 50 mL of 5.0 x 10-4 M AgNO3 solution. 3. Hydrogen peroxide: 0.050 M. Calculate the volume of 1.4 M H2O2 solution needed to prepare 50 mL of 0.050 M H2O2 solution. 4. Sodium borohydride: 0.015 M. Calculate the volume of 0.15 M NaBH4 solution needed to prepare 25 mL of 0.015 M NaBH4 solution.
The following four stock solutions are used for the preparation of AGNP:
1. Sodium citrate: 0.015 M
2. Silver nitrate: 5.0 x 104 M
3. Hydrogen peroxide: 0.050 M
4. Sodium borohydride: 0.015 M
To investigate the factors which affect nanoparticle formation and to optimize the formation of
nanoplates (nanoprisms), solutions 1-3 plus high purity (Millipore) water are combined in
separate test tubes according to the following table:

Nanoparticle formation is started by the addition of 1.0 mL of solution 4 to each of the above
tubes, then briskly stirred. All reactants are colorless in solution, but once combined and after a
brief induction period, a color change occurs. In some cases, the initial solution color changes to
a different color or goes through multiple color changes before a final constant color is achieved.
The absorbance spectrum of each solution in the range 375-950 nm is then recorded. These
spectra are compiled and presented in part c of the activity. These experimental results were
obtained by students who performed this experiment in general chemistry lab several semesters
ago.
