Question

select the two products of the double replacement reaction below?

pb(clo₃)₂(aq) + bacl₂(aq) -->?? +???

cl₂clo₃(aq)

ba(clo₃)₂(aq)

pbcl₂(s)

bapb(s)

Explanation:

Step1: Understand double - replacement reaction

In a double - replacement reaction \(AB + CD
ightarrow AD+CB\). Here, \(A = Pb^{2 +}\), \(B=(ClO_{3})^{-}\), \(C = Ba^{2+}\), \(D = Cl^{-}\)

Step2: Write the products

The products will be \(PbCl_{2}\) and \(Ba(ClO_{3})_{2}\). According to solubility rules, \(PbCl_{2}\) is insoluble (\(s\) for solid) and \(Ba(ClO_{3})_{2}\) is soluble (\(aq\) for aqueous)

Answer:

B. \(Ba(ClO_{3})_{2}(aq)\), C. \(PbCl_{2}(s)\)
