Abstract
The electrostriction of aqueous hydrogen and hydroxide ions at infinite dilution was calculated by the shell-by-shell method over the temperature range 0 to 200 °C. The calculation required an estimate of the ionic radius of these ions, and comparison with data for aqueous lithium, sodium, and fluoride ions provided values for the nominal sizes of the hydrogen and hydroxide ions in solution. From the volumetric standpoint, these sizes are surprisingly smaller than the size of a water molecule.
