It is prepared from nitrobenzene by reducing it with stannous chloride and sodium hydroxide.
stannous chloride is usually sufficiently contaminated with stannic salt.
The colour is developed gradually as the temperature rises; it may be rendered brighter by the addition of stannous chloride.
Note the quantity of the stannous chloride solution required.
Brown precipitates are formed by both hydrogen sulfid and ammonium sulfid, in stannous solutions.
These reactions are characteristic of tin as stannous chloride.
Boiling with stannous chloride solution reduces it to the metal; digestion with potassium iodide gives mercurous iodide.
The tin should be reported as stannous oxide; and is calculated by multiplying the percentage of tin by 1.136.
The antimony is precipitated as metal, and the tin remains in solution as stannous chloride.
stannous chloride (protomuriate of tin), produces an isabel yellow precipitate.
stannous stan·nous (stān'əs)
Of, relating to, or containing tin, especially with valence 2.
Containing tin, especially tin with a valence of 2. Compare stannic.
