  • Ammonia vs. Ammonium – what is the difference between these . . . - Hach
    Ammonia and ammonium are different forms of nitrogen The major factor that determines the proportion of ammonia to ammonium in water is pH The activity of the ammonia is also influenced by ionic strength and temperature It is important to remember as un‐ionized NH 3 can be harmful to aquatic organisms, while ionized ammonium is basically harmless The chemical equation that drives the
  • Chemistry Explained: Hardness - Hach
    Traditionally, either murexide indicator (ammonium purpurate) or Eriochrome Blue-Black R indicator is followed by titration with EDTA CalVer 2 Calcium Indicator has been developed by Hach to replace these indicators CalVer 2 (hydroxy naphthol blue) is more sensitive and has a sharper end point color change
  • What is the best way to prevent contamination when doing TKN and . . . - Hach
    The process of drying the tubes can contribute to contamination Water droplets pick up ammonium chloride from the air, they evaporate and deposit the salts on the walls of the tubes Minimize the amount of time digestion solutions are exposed to the atmosphere

  • Will the Ammonia (Nitrogen) Test Strips, 0-6. 0 mg L detect . . . - Hach
    The Ammonia (Nitrogen) Test Strips, 0-6 0 mg L (Product # 2755325) will not detect quaternary ammonium compounds or residues The test strips work by raising the pH of the sample to above 10 which converts all ammonium ions in the sample to free (un-ionized) ammonia Quaternary ammonium cations are permanently charged cations, independent of pH, so they do not get converted to free ammonia

  • What are the possible interferences with the Hydrogen Peroxide . . . - Hach
    Method information: The first reagent is the ammonium molybdate solution It consists of molybdate and sulfuric acid The molybdate is a catalyst for the reaction, and the acid brings the pH down, which is optimal for the test Then the Sulfite 1 reagent is added This reagent contains potassium iodide and starch (starch iodine redox titration )
  • Sind Ammoniak (NH3) und Ammonium (NH4+) unterschiedliche Stoffe?
    Ammoniak (NH3) und Ammonium (NH4) befinden sich in Wasser gelöst im Gleichgewicht Das Verhältnis von NH3 und NH4+ in der Probe variiert je nach Druck, Temperatur und vor allem pH-Wert In basischen Lösungen liegt es als Ammoniak vor Dies muss unbedingt beachtet werden Auch wenn der Messwert mit anderen Geräten verglichen wird, die NH3 oder NH3-N anzeigen
