Webb3 feb. 2024 · The given 0.205 M ammonia is the total concentration for both forms of that species, the acid and the base, NH3 and NH4+. However, for a weak base like ammonia, we can assume that the amount of NH3 that has been changed to NH4+ is so low (by a magnitude 5x less than 10, given by the kb) that doing the calculation wouldn't change … WebbThe pH of 0.1-molar ammonia is approximately...
