Tin(II) chloride, also known as stannous chloride, is a white crystalline solid with the formula Sn Cl 2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot. SnCl 2 is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating.
The next step is to add dilute stannous chloride reagent, which has been freshly prepared from concentrated stannous chloride reagent and distilled water, to the mixture in the tube. This will produce a blue colour (due to the formation of molybdenum blue ) and the depth of the blue colour indicates the amount of phosphate in the boiler water.
The tin(II) chloride reduces the chloroauric acid from the dissolution of gold in aqua regia to a colloid of elemental gold supported on tin dioxide to give a purple precipitate or coloration. When used as a test, the intensity of the color correlates with the concentration of gold present.
Tin(II) chloride (also known as stannous chloride) is the most important commercial tin halide. Illustrating the routes to such compounds, chlorine reacts with tin metal to give SnCl 4 whereas the reaction of hydrochloric acid and tin produces SnCl 2 and hydrogen gas.
Chlorides are confirmed by the chromyl chloride test. When the salt is heated with K 2 Cr 2 O 7 and concentrated H 2 SO 4, red vapours of chromyl chloride (CrO 2 Cl 2) are produced. Passing this gas through a solution of NaOH produces a yellow solution of Na 2 CrO 4. The acidified solution of Na 2 CrO 4 gives a yellow precipitate with the ...
