Prepn by reduction of the tetrachloride: Ingraham et al., Inorg. Synth. 6, 52 (1960); Sherfey, ibid. 57.
Properties
Dark red-violet, unstable, deliquesc crystals;
dec on heating above 500°. The dry powder is pyrophoric in air.
Very reactive and readily dissociated by moisture in air. Sol in
water, exothermic process; sol in alcohol. Practically insol in ether.
Keep tightly closed.Use
A powerful reducing agent. Reduces nitrate to ammonia;
when boiled with aq SO
2, sulfur is separated; hence is
used as an aq soln for estimation of nitro groups, ferric ions, per-salts,
etc. Removes stains, etc. (stripper) in laundering.
