Which of the following observations would be the expected indication that a reaction has taken place when a solution of cesium sulfate is mixed with strontium perchlorate. Bubbling
Formation of percipitate
Formation of soluble salts
Formation of a gas

Formation of precipitate

Formation of soluble salts

Explanation:

Let's consider the molecular equation that takes place when an aqueous solution of cesium sulfate is mixed with an aqueous solution strontium perchlorate.

Cs₂SO₄(aq) + Sr(ClO₄)₂(aq) ⇒ 2 CsClO₄(aq) + SrSO₄(s)

According to the solubility rules:

For a double displacement reaction to occur, at least one of the products must be insoluble or volatile.

It's b) Formation of a precipitate
