15362 IUPAC Gold Book - solvent volume fraction 10.1351/goldbook.15362 15362 current 1 For a solvent \(\ce{A}\), volume fraction of \(\ce{A}\) divided by the sum of the volume fractions of solvent in a solution containing both \(s\) solutes (\(i = 1, 2, \ldots, s\)) and \(p\) solvents (\(i = s + 1, s + 2, \ldots, p\)) \[\varphi_{{\rm{v}},{\ce{A}}} = \varphi_{\ce{A}}/\sum \limits_{i=s+1}^{p} \varphi_{i}\] where the summation is over the \(p\) solvent components only. Used to express solvent composition for a system containing a solute in a mixed solvent. components https://goldbook.iupac.org//terms/view/16268 PAC, 2008, 80, 233.
