Strontium acetate is the strontium salt of acetic acid with the constitutional formula Sr (CH ₃ COO) ₂ .

Manufacturing

Strontium acetate, by reaction of strontium carbonate or strontium are shown with acetic acid.

${\displaystyle \mathrm {SrCO_{3}+2\ CH_{3}COOH\rightarrow Sr(CH_{3}COO)_{2}+H_{2}O+CO_{2}\uparrow } }$

${\displaystyle \mathrm {Sr(OH)_{2}+2\ CH_{3}COOH\rightarrow Sr(CH_{3}COO)_{2}+2\ H_{2}O} }$

properties

Strontium acetate crystallizes in the cold as a tetrahydrate, at room temperature as a hemihydrate .

Strontium acetate decomposes at approx. 380 ° C with the formation of strontium carbonate.
