Stannous chloride dihydrate
CAS NO.10025-69-1
MF:Cl2H4O2Sn
MW:225.65
1.Performance and use:
There are anhydrous substances and hydrates. The former is a transparent crystal with a melting point of 246 ºC, a boiling point of 652 ºC, and a relative density of 3.95. Can dissolve in water and be oxidized in air to form insoluble chlorine oxides. Hydrolysis of Chemicalbook in water generates precipitation of basic stannous chloride [Sn (OH) Cl]. When preparing its solution, it needs to be dissolved in concentrated hydrochloric acid and then diluted to inhibit hydrolysis. Due to its susceptibility to air oxidation, adding metal tin particles to the solution can prevent oxidation.Used for colorimetric determination of silver, lead, arsenic, molybdenum, etc., and also used as a reducing agent and mordant
