I'm reading Shrivers Inorganic Chemistry book and some of the equations have a (sol) state on them. I'm sure the book has already defined this but I cannot find where. Examples:
\begin{align} \ce{[NH3OH]Cl (sol) + NaOBu &-> NH2OH (sol) + NaCl (s) + BuOH (l)}\\ \ce{SbF5 (l) + HF (l) &-> H2F+ (sol) + SbF6- (sol)} \end{align}
