MOPS/EDTA Buffer, 10X Liquid Concentrate, Molecular Biology Grade - Calbiochem Prepared with DEPC for RNA applications. how much quantity of sodium acetate and acetic acid do i have to add to get the exact pH. I am a bit confused in preparing acetate buffer using na acetate and acetic acid. I need to prepare 50 mM of sodium acetate buffer at pH 5.4 and then adjust its molarity to 0.1, 0.2 and 0.5 M using NaCl alone. It is very popular in hematology, since there is some evidence that acetate When an acetic acid (sodium) buffer solution is prepared from 1:1 acetic acid and sodium acetate, for example, the buffer solution pH is approximately 4.7 (near the acetic acid pKa), and this is where the maximum buffer action can be obtained.
Add the volume of X M sodium acetate solution (V NaAc) equivalent to 50 mmol in a 1 L container containing 400 mL of distilled water with the electrode of the pH meter. 1X GlycoBuffer 2: 50 mM Sodium Phosphate (pH 7.5 @ 25°C) 1X GlycoBuffer 3: 50 mM Sodium Acetate (pH 6.0 @ 25°C) 1X Glycoprotein Denaturing Buffer 0.5% SDS, 40 mM DTT 1% NP-40 Kit Components.
