Question

What hapoens when an aqueous solution of sodium sulphur reacts with an aqueous solution of barium chloride . State th physical condition of reactants in which the reaction between them will not take place.Write the balanced chemical equation for the reaction and name the type of reaction.

Answer 1

BaCl2(colourless) + Na2SO4(colourless)...........BaSO4(white precipitate) + 2NaCl

Answer 2

Answer:

A white ppt. ( precipitate ) is formed.

Na₂SO₄ ( aq ) + BaCl₂ ( ag ) ⇒  2 NaCl ( aq ) + BaSO₄ ( ↓ )

Doubled Displacement reaction

The reaction in which there is an exchange of ions between the reactants.
