Sodium Acetate → Sodium Diacetate

Participants

Reaction Steps

Subsequently, an experiment was performed to obtain a favorable pH value for a measuring solution of acetic acid-sodium acetate. With a standard 0.2M acetic acid solution with a pH value of 2.7, a sodium acetate was added to the measuring solution used in the experiment to adjust pH, and resulting 0.2M acetic acid-sodium acetate buffer solutions having pH4.0, 5.0, 6.0 and 6.97 were each used. Also, as in the experiment 4, a solvent containing a standard humic-like substance and 2 middle mature composts (composts C and D) will be measured and the absorbancy was measured for the solid-liquid separation supernatant (liquid phase) in compost extracts. The results are shown in FIGS. 11 to 13.
