ammonium acetate solution preparation

Adjust the volume to 100 mL with H2O. Preparation Procedure 1 (1) Add the indicated amount(s) of mobile phase additive(s) to 950 mL of water. To prepare a 10 M solution in 1 L, dissolve 770 g of ammonium acetate in 800 mL of H2O. Adjust volume to 1 L with H2O. Alkaline Buffers. Sodium acetate buffers are used for purification and precipitation of nucleic acids, as well as for protein crystallization and staining gels used in protein electrophoresis.

How did you discover this? 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). In this case, we have to prepare 50 mL of 200 mM ammonium acetate solution in pure water. Raise or lower the pH to the desired level. Because of this, it has been used to replace cell buffers with non-volatile salts in preparing samples for mass spectrometry. As the salt of a weak acid and a weak base, ammonium acetate is often used with acetic acid to create a buffer solution. Strong acids, strong bases and most salts are strong electrolytes.
