    Question about ammonia and TAN for a small experiment

    Hello! I am trying to set up a small experiment for my class but I am stuck on a problem. We have three saltwater tanks, with the following measurements: The first tank will have a pH of 7.5, an NH3 level of 0.06 mg/L, and a TAN (total ammonia nitrogen) level of 20. Just NH3 is added. The...

    Nitrogen and Lone Pairs in Mimisine

    Hey all, I'm having some trouble pinning down the lone pairs on this Mimisine molecule. The problem says to complete the structure of a line-structure drawing of Mimisine by drawing in the Hydrogens and lone pairs, which, as you can see in the attached picture, I've mostly done. What's giving...

    purification of sodium chloride, especially removal of nitrogen and phosphorus

    Hi everyone, I would like to purify NaCl, especially remove N and P compounds (most importantly inorganic, but also organic if possible). Background: I'm analysing inorganic and organic N and P in saline environmental samples using colorimetric flow injection analysis, and may need fairly...

    Lewis structure for Nitrogen Dioxide

    I was able to come up with a total of 7 possible Lewis structures of Nitrogen Dioxide (NO2). I am convinced that some of them are incorrect but I'm not sure of the reason why. They all count electrons correctly, but their formal charges are different. Which ones are correct and which ones are...
