Hydrated ionic liquids can be used as buffers, according to scientists have shown that it is possible to control proton activity, or pH, in concentrated ionic media. These ionic liquid buffers can help to establish and maintain pH in a variety of ionic liquid applications where solutes or processes are highly sensitive to proton activity in the medium.
Douglas MacFarlane and colleagues from Monash University, in Australia and co-workers based at the University of North Carolina at Charlotte, in the US, have reported their findings in ChemComm.
