Using what we have learned in CHEM 2310 and up through class on 1/31, propose a series of reaction
steps to achieve the transformation below. Be sure to show all reagents and intermediates for full
credit. You do not need to draw mechanism arrows, but you do need to include charges where
appropriate. If you do not put your group name, you will get half credit at most.

A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer.
