Will strontium bromide and potassium sulfate give a precipitate
antiseptic1488 [7]

Answer:- Yes, strontum bromide and potassium sulfate gives a precipitate of strontium sulfate.

Explanations:- As per the solubility rules, all compounds of alkali metals are soluble.

Sulfate of most of the alkaline earth metals like Ca, Ba and Sr are insoluble.

A double displacement reaction takes place when strontium bromide and potassium sulfate are mixed and a precipitate of strontium sulfate is formed:

Sr(Br)_2(aq)+K_2SO_4(aq)\rightarrow 2KBr(aq)+SrSO_4(s)

Note: (aq) stands for aqueous and (s) stands for solid and here it's precipitate.
