Peracetic acid has a molecular weight of 76.05. Its dissociation constant (pKa) is 8.2 at 20°C and therefore, the substance is mainly present in th environment as peracetic acid at a neutral pH (pH =7), while peracetate (the salt of Peracetic acid) would mainly be present if the pH is significantly higher than8.2 (OECD 2008). The pH of Peracetic Acid solution is reported to range fro 1 to 1.8 (OECD 2008:US National Library of Medicine 2012;NOAA 2015).
