What happens when aqueous solutions of Sodium sulphate and Barium chloride are mixed? Give a balanced equation for the reaction with state symbols. Name and define the type of chemical reaction involved in the above change.
Answers
When an Aqueous solution of the sodium sulphate is mixed with the Barium Chloride solution, then they will form precipitate of the Barium sulphate and Sodium Chloride.
Reaction will be,
BaCl₂ + Na₂SO₄ ---------- 2NaCl + BaSO₄
BaCl₂ = Barium Chloride
Na₂SO₄ = Sodium Sulphate
NaCl = Sodium Chloride
BaSO₄ = Barium Sulphate
__________________________________
This Reaction is the Double displacement reaction.
It may be defined as the Reaction in which the radicals are exchanged. For example, Cl of Barium chloride and SO₄²⁻ of Sodium sulphate is exchanged to form a new products.
Hope it helps.
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.
