Write the balanced chemical equation for the reaction of barium chloride with so

Question

Write the balanced chemical equation for the reaction of barium chloride with sodium sulfate in presence of nitric acid. Identify physical state of each product. Write the net ionic equation for this reaction. You are asked to analyze an aqueous solution (X) and determine what's in it. You pour some of your sample X into a test tube and add a few drops of an acid. No observable reaction occurs. Then you add a few drops of barium chloride solution to your mixture (containing an aqueous solution X and the acid), a white precipitate forms. What can you conclude about the solution X? (Circle as many choices as applies.) Solution X must contain a covalent (molecular) compound Solution X does not react with barium chloride. This experiment is inconclusive, and does not provide any information about the contents of X. Solution X must contain sulfate ion. Solution X Does not contains any ionic compound. The solution X contains an ionic compound.

Explanation / Answer

BaCl2 (aq)+ Na2SO4(aq) BaSO4 (s)+ 2NaCl(aq)

The white precipitate of BaSO4 is formed by the reaction of SO42-and Ba2+. The other product formed is sodium chloride which remains in the solution. Such reactions in which there is an exchange of ions between the reactants are called double displacement reactions.
