Ionized vs unionized ammonia

Web10 mrt. 2024 · The equilibrium of Equation 3.16 depends on pH and temperature, (see Figure 3.6). In a laboratory analysis, total ammonia (NH3 + NH4+) is measured and the distribution between unionized ammonia (NH3) and ionized ammonia (NH4+) is calculated from knowledge of the water pH and temperature at the sampling site. WebOf the two, the free ammonia form is considerably more toxic to organisms such as fish and, therefore, we pay considerable attention to the relative concencentration of this particular contaminant. Lastly, this free ammonia is a gaseous chemical, whereas the NH4+ form of reduced nitrogen is an ionized form which remains soluble in water.
