Ammonia (NH3) is toxic to fish at a concentration of 0.01 mg/L NH3-N, but ammonium (NH:) has negligible toxicity. What is the maximum concentration (in mg/L) of total ammonia nitrogen (the sum of ammonia and ammonium) that can be in solution without causing toxicity at (a) pH 8 and at (b) pH 10? Note: "NH3-N" and "ammonia nitrogen" means that only the mass of the nitrogen atom is counted. That is, this is treating both ammonia and ammonium as having...
