Strontium hydroxide

It is synthesized by combining a strontium salt with a strong base.

Because Sr(OH)2 is slightly soluble in cold water, its preparation can be easily carried out by the addition of a strong base such as NaOH or KOH, drop by drop to a solution of any soluble strontium salt, most commonly Sr(NO3)2 (strontium nitrate).

From here, the solution is filtered, and the Sr(OH)2 is washed with cold water and dried.

[3] Strontium hydroxide is used chiefly in the refining of beet sugar and as a stabilizer in plastic.

Strontium hydroxide is a severe skin, eye and respiratory irritant.
