Answer to Question #178781 in Chemistry for Karley Eilts

Question

What are the spectator ions if the following substances are placed in the beaker to react?

BaNO3(aq) + Na2SO4(aq)

Answer 1

The reaction between the substences:

Ba(NO₃)₂(aq) + Na₂SO₄(aq) = 2NaNO₃(aq) + BaSO₄(s)

The ionic equations for the reaction:

Ba⁺(aq) + 2NO₃^-(aq) + 2Na(aq) + SO₄^2-(aq) = 2Na⁺(aq) + 2NO₃^-(aq) + BaSO₄(s)

Here, N⁺ and NO₃^- are spectator ions because do not take part in the reaction and are present in the solution both before and after the reaction.
