Abstract
The degree of dissociation (α) of HClO4 in 2–12M aqueous solutions has been determined by measuring the Raman intensity of the 931‐cm−1 ClO4— band. These measurements indicate that the acid is completely dissociated at concentrations up to 8M. Throughout the range of these experiments, α is found to be significantly higher than the values in the literature which were obtained by the use of proton magnetic resonance spectroscopy. The temperature dependence of α was found to be very small.Keywords
