In the reaction below, how many molecules of water can be produced from 40.7 g of sodium hydroxide and excess chlorine? The relative contribution of unionized versus ionized forms to total ammonia concentrations depends on certain water quality criteria, most notably pH: as pH increases, so does the proportion of ammonia in its unionized form. In addition to observations of the sources discussed above, observational evidence at the site may suggest that high ammonia should be included as a potential candidate cause: Slow-moving water: Slow-moving or stagnant water (see Figure 5) may have high ammonia concentrations because of lack of turbulence and volatilization and greater accumulation of metabolic waste and decomposition productsincluding ammonia (WHO 1986). So From the statement magnesium hydroxide reacts with nitric acid to produce magnesium nitrate and water, identify the reactants and the products.
