It is a white powder that is used as an electrolyte in nonaqueous electrochemistry. It is highly soluble in polar organic solvents such as acetone and acetonitrile. The salt consists of a positively charged tetrabutylammonium, a quaternary ammonia cation and a weakly basic hexafluorophosphate anion. These species are chemically inert, which allows the salt to serve as an inert electrolyte over a wide potential range. Given the sensitivity of electrochemical experiments, this salt is usually further purified, e.g., by recrystallization from aqueous or absolute ethanol.[1] References1. ^{{cite book | author = Zoski, Cynthia G. | title = Handbook of Electrochemistry | edition = 1st | location = Amsterdam | publisher = Elsevier | year = 2007 }} {{Hexafluorophosphates}} 2 : Quaternary ammonium compounds|Hexafluorophosphates |
