* Data below were taken from James Schwabacher's [[User:James C. Schwabacher/Notebook/CHEM-571/2014/09/19|entry]]: | |||
*Mercury stock solution | |||
# 0.0908g HgCl2 | |||
## (0.0908g HgCl2)*(1mol HgCl2/271.5g HgCl2)*(1mol HgCl2/1mol Hg)*(200.59g Hg/1mol Hg) = 0.0671g Hg | |||
## put in 250mL volumetric | |||
## 268ppm Hg | |||
*Arsenite solutions for vials from 0.0499 mol/L (3738.588 ppm As) stock. These were made by me and Eleni for the entire class. | |||
# 4 mL of stock in 100 mL volumetric flask -> 150 ppm As | |||
# 2.67 mL of stock in 100 mL volumetric flask -> 100 ppm As | |||
# 1.337 mL of stock in 100 mL volumteric flask -> 50 ppm As | |||
*Mercury solutions for vials from 268 ppm Hg stock. These were prepared by me and Madeleine, to split between our groups. | |||
# 27.985 mL of stock in 50 mL volumetric flask -> 150 ppm | |||
# 18.657 mL of stock in 50 mL volumetric flask -> 100 ppm | |||
# 9.328 mL of stock in 50 mL volumteric flask -> 50 ppm | |||
