Bischlorous acid strontium salt
Bischlorous acid strontium salt Usage And Synthesis
Strontium chlorite is not offered for sale commercially, due in part to the cost of strontium as compared to the same calcium salt which is just as effective as an oxidizing agent.
Strontium chlorite, Sr(ClO2)2, has the molecular
weight of 155.072 g/mol. Its density is 2.61 g/cm3. Its
CAS number is 14674-72-7. Its melting point is 757°C and it has a boiling point of 1484°C. Strontium chlorite
can be prepared by reaction of chlorous acid with strontium carbonate:
SrCO3 (s)＋ 2HClO2 (aq)→Sr(ClO2)2·6H2O
It is a white granular solid and, if formed in solution, crystallizes as the hexahydrate. Like its calcium homologue, strontium chlorite is a strong oxidizing agent. It accelerates the burning of combustible materials, ignites on contact with potassium thiocyanate and reaction with chlorine yields explosive chlorine dioxide gas. Reaction with ammonia produces ammonium chlorite, which is shock sensitive. If mixed with finely divided metallic or organic substances, the combination is highly flammable and may be ignited by friction.
