Antimony pentachloride is a very corrosive substance, and fumes in moist air. It reacts with water vigorously to give a strongly acidic solution consisting mainly of hydrochloric acid (with some dissolved antimony(V)). This is due to the hydrolysis of this compound. It is very soluble in hydrochloric acid and solutions containing the chloride ion, due to complex formation:
SbCl5 + Cl- → SbCl6-
