Abstract
Degrees of dissociation of methanesulphonic acid in aqueous solution at 25°C have been determined from integrated intensity measurements on the 1051 Δ cm–1 Raman band characteristic of methanesulphonate ions. The results are in disagreement with previous estimates and indicate that methanesulphonic acid is stronger than nitric acid, having a dissociation constant of about 73 mole/l.Keywords
