What's the formula equation for the reaction that occurred between the barium chloride solution , BaCl2 (aq), and the sodium sulfate solution, Na2SO4(aq).

The balanced equation is:

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

This is a double replacement reaction.

The reactants are:

a) BaCl2: barium chloride, a ionic compound, therefore soluble in water,

b) Na2SO4: sodium sulfate, another ionic compound, therefore also soluble in water.

The products are:

c) BaSO4: barium sulfate, a solid not soluble in water which precipitates.

d) NaCl: sodium chloride, an ionic compound, therefore soluble in water.
