Strontium hydroxide = Sr(OH)2
To produce strontium chloride (SrCl2), we need to supply the chloride part (Cl), and since strontium hydroxide is a base, we want an acid that has the chloride ion. That would most easily be hydrochloric acid, HCl. So the reaction would look like this ...
Sr(OH)2 + 2HCl ==> SrCl2 + 2H2O
