Ammonium acetate is soluble in plain water up to something around 18 M. It should then completely dissolve for a 10 M solution. Acid/base chemistry; Dissociation equilibrium; Droplet evaporation; Henderson-Hasselbalch equation; Noncovalent complexes in the gas phase. A deliquescent white crystalline solid, it has a relatively low melting point (114°C) for a salt.

Ammonium Acetate EC50 Daphnia magna (Water flea) (mg/l - 48hr): 56 Section 13: Disposal considerations General information Dispose of in compliance with all local and national regulations. Ammonium acetate is non-toxic, though if heated it can generate acetamide which is considered carcinogenic. The molar concentration of ammonium acetate buffer in the mobile phase significantly affected the retention and resolution. Ammonium acetate can be purchased online cheaply. Used as a food acidity regulator, although no longer approved for this purpose in the EU. 1996 Apr 2;35(13):4069-78 58 / Monday, March 26, 2012 / Rules and Regulations Date of issue: 10/03/2007 Revision date: 05/04/2018 Supersedes: 11/01/2016 Version: 1.2 05/04/2018 EN (English US) Page 1 SECTION 1: Identification . Graphical Abstract ᅟ. Keywords: For example, sodium chloride breaks into sodium (Na+) and chloride (Cl-) ions that exist in aqueous form in the water. J Chromatogr A. MDL number MFCD00013066. Ammonium acetate is made from ions, ammonium and acetate, that themselves are weakly acidic and basic, respectively. In laboratory conditions, ammonium acetate can be obtained as follows: add 10% NH4OH solution to 80% CH3COOH under cooling water and vigorous mixing until the solution has a strong odor of ammonia. Ammonium acetate is volatile at low pressures and has a vinegar-like smell. J Am Soc Mass Spectrom. -, Proc Natl Acad Sci U S A. A deliquescent white crystalline solid, it has a relatively low melting point (114℃) for a salt. Buffer table - ammonium acetate Per liter. The optimum buffer concentration is 1 M. Below 0.5 M, excessive retention and peak broadening results, particularly in isocratic elution. By definition, a buffer consists of a weak acid and its conjugate weak base.

Ammonium acetate does provide buffering around pH 4.75 (the pK a of acetic acid) and around pH 9.25 (the pK a of ammonium). The compound ammonium acetate is a strong electrolyte. 2004 May 28;1037(1-2):455-65. doi: 10.1016/j.chroma.2003.07.018. Clipboard, Search History, and several other advanced features are temporarily unavailable. Dyes possess poor levelling property due to very high affinity and consequent higher strike rate for fibre. It is non-volatile, highly soluble in water and, based on its chemical properties, is not expected to leach to groundwater. 2013 Dec;86:11-35. doi: 10.1016/j.jpba.2013.07.013.
