een the reactants are called double displacement​

Answer 1

WHAT TYPE OF REACTION IS THIS?

• The above given reaction between SO4²‐ and Ba²+(in the original reaction) is both a double displacement and a precipitation reaction.

1. It is a double displacement reaction because two compounds have exchanged their ions in a reaction.
2. It is a precipitation reaction because a white insoluble substance of BaSO4(s) is formed which in insoluble in water.

The reaction is as follows ::::::::::::

Na2SO4(aq) + BaCl2(aq) -----------> BaSO4(s) + NaCl(aq)

precipitate

IN this reaction the percipitate(ppt) remains insoluble in the solution while the other product which is NaCl remains dissolved in the solution.

Hence, the individual reaction between SO4²- & Ba²+ yields the ppt of BaSO4(s).
