5470-11-1 Usage
Reactivity Profile
A powerful reducing agent. Reacts with bases and oxidizing agents.
Air & Water Reactions
Hygroscopic. Sensitive to prolonged exposure to air. Water soluble. Reacts slowly with water.
Purification Methods
Crystallise the salt from aqueous75% ethanol or boiling methanol, and dry it under vacuum over CaSO4 or P2O5. It has also been dissolved in a minimum of water and saturated with HCl; after three such crystallisations, it is dried under a vacuum over CaCl2 and NaOH. Its solubility at 20o is 85% in H2O, 6% in EtOH and 12% in MeOH. [Hurd Inorg Synth I 87 1939, Semon in Org Synth Coll Vol I 318 1941.]
