# What does (sol) in a chemical equation mean?

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}

The state (sol) or (solv.) stands for "solvated". Since you are dissolving $$\ce{HF}$$ in liquid $$\ce{SbF5}$$, there is no water in that system (which would cause hydrolysis). So it is not correct to use (aq), since it is a nonaqueous system.
• Autoprotolysis of liquid ammonia: $$\ce{2NH3 (l) <=> NH4+ (sol) + NH2- (sol)}$$
• Autoprotolysis of nitrosyl chloride: $$\ce{NOCl (l) <=> NO+ (sol) + Cl- (sol)}$$
• Dissolving sodium metal in liquid ammonia creates solvated electrons: $$\ce{Na (s) <=> Na+ (sol) + e- (sol)}$$
