Bookmark or Share- Ammonia vs. Ammonium – what is the difference between these ... - HachAmmonia 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 ...

- Chemistry Explained: Hardness - HachThe traditional test for hardness involves pH adjustment to 10.1 with an ammonium buffer, addition of Eriochrome Black T indicator [1-(1- hydroxy-2-naphthylazo)-6-nitro-2-naphthol-4-sulfonic acid] and then titration with Na2EDTA (ethylenediaminetetraacetic acid, disodium salt) solution.
- What concentration of ammonia is toxic to fish?Ammonia exists in water as either the ammonium ion (NH4+) or the un-ionized ammonia (NH3). Un-ionized ammonia is toxic to fish, while the ammonium ion is nontoxic except at extremely high concentrations. At neutral pH 7 and ambient temperature, almost all of the ammonia exists as NH4+.
- Where can I find information on how to determine ammonium using the ...Ammonium ions react with hypochlorite ions and salicylate ions as a catalyst for indophenol blue at pH 12.6 in the presence of sodium nitroprusside. Application: Surface water, waste water, soil eluate, substrate solutions Measurement ranges: LCK302: 47 - 130 mg/L NH 4-N or 60 - 167 mg/L NH 4 LCK303: 2 - 47 mg/L NH 4-N or 2.5 - 60 mg/L NH 4
