Since ammonium acetate is hygroscopic, it is quite challenging to produce this compound in crystalline form.

NH4+ and CH3-COO- are not a conjugate acid/base pair, which means that they do not constitute a buffer at pH 7. Any eye contact with this compound can result in rashes. The compound serves as one of the best sources of ammonia is the Borch reaction during organic synthesis. COVID-19 is an emerging, rapidly evolving situation. Mise à jour : 1986-09-24. Take, for example, almost all the different varieties of substances or mixtures in aqueous solutions resist changes in pH with the addition of small quantities of ammonium acetate bases or acids. 7.89 g/100 cm³ (méthanol, 15 °C). Ammonium acetate does provide buffering around pH 4.75 (the pKa of acetic acid) and around pH 9.25 (the pKa of ammonium). Native ESI-MS involves the transfer of intact proteins and biomolecular complexes from solution into the gas phase. -, Mass Spectrom Rev.
