pKa values in SoftAcid

SOFTACID TECHNICAL BULLETIN:  pKa VALUES

Ka differs for each acid and varies over many orders of magnitude. The acidity constant is often represented by the additive inverse of its common logarithm, represented by the symbol pKa (using the same mathematical relationship as [H+] is to pH). In general a smaller value of pKa indicates a stronger acid, since the extent of dissociation is larger at the same concentration.

SoftAcid is a range of products consisting of organic acids and modified lignosulphonic acids. These products will contain acid groups with pKa over a broad range, giving SoftAcid a very favourable profile.
