Jan 30, 2020 · Preparation of standards in Standard Methods: all the methods refer back to SM 4500 NH3 D section (3)(d) which states: stock ammonium chloride solution: Dissolve 3.819 g anhydrous NH4Cl (dried at 100° C) in water, and dilute to 1000 mL. 1.00 mL = 1.00 mg N = 1.22 mg NH3. That solution equals a 1000 mg/L concentration of Ammonia as Nitrogen.
