Question
How to calculate the concentration of each standard in ppm NO3- as N. And I would like to know how to do number 8. Preparation of Solutions. 100 ppm NO3- as N. Dissolve, 0.152 g NaNO3 (accurately weighed) in distilled water and dilute to 250.0 mL in volumetric flask. Make this solution first and transfer ~100 mL of solution to small beaker and begin soaking the nitrate electrode making sure the small white reference contacts are immersed. The nitrate electrode must be equilibrated in this solution for at least 30 minutes. 2.0 M (NH4)2SO4 Ionic Strength Adjuster. Dissolve 26.42 g of (NH4)2SO4 in distilled water and dilute to 100.0 mL in a volumetric flask....Explanation / Answer
Verification:
Solution from A.1 is 100 mg N/mL (i.e.,100 mg N/g solution, i.e.,100 ppm N, not NO3-).
85 g NaNO3
