Assume, 1 mole of each was added to $1L$ solution of water.43% of ammonia molecules are converted into ammonium. To quote from the abstract: Previous studies have shown that the toxicity of ammonia to freshwater fishes depends on the ambient concentration of the un-ionized fraction (NH3) and have quantified the percent NH3 in solution as a function of temperature and pH. Amoni hydroxit là một dung dịch bazo yếu, phân hủy thành khí NH3 và nước.09(1 mM solution);10. In pure form, it is a clear liquid that smells strongly of ammonia. This is because any dissociating NH4+ will react with water over chloride and form NH4OH making the solution basic. NaOH + X -> NaCH3COO + H2O What is X in this reaction? pH = pKa + log [salt] / [acid] This relationship is called Henderson’s equation.
