  2. Tin (II) chloride - Wikipedia

    en.wikipedia.org/wiki/Tin(II)_chloride

    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. This test was first observed and refined by a German ...
