Appearance and odour: clear liquid, odour reminiscent of vinegar

Packaging: professional wide necked, white HDPE bottle with blue conical seal cap and tamper ring. Labelled. Bottle and cap are UN approved and reusable.

Description and uses:

This is a master solution of 1 M sodium acetate/acetic acid which on dilution yields a buffer solution of pH = 4.7.

Dilute 100 ml (content of the bottle you receive) to approx. 500 ml or 1000 ml final volume, with deionised or very soft mineral water. Lower dilution gives highest buffering capacity but final pH is always 4.7.

One of the most used and most stable buffering solutions available.
