The pKa for formaldehyde is determined to range from 12.79-13.27 at temperatures ranging from 23-30°C.
Three sources were identified
concerning the dissociation constant of formaldehyde. According to the
online database HSDB (2015) the pKa at 25 °C is 13.27. This value
is supported by Reaxys wich reported a pKa of 12.79 at 23 °C (Wadano
1934) and a pKa of 12.87 at 30°C (Levy 1933).
