Decomposition of urea
WebAmmonia (NH_3) is a basic gas produced by the decomposition of urea. A major emission source of ammonia is concentrated animal feeding operations (CAFOs). Determine the equilibrium pH of initially pure water that is exposed to air containing 36 ppb of ammonia, typical of polluted urban environments.
