Question

what happens when an aqua solution of sodium sulphate reacts with an aqua solution of Barium Chloride write the equation for the reaction​

Answer 1

Answer:

When barium chloride reacts with sodium sulfate, it leads to the production of barium sulfate and sodium chloride. This reaction is a type of double displacement reaction because here, exchange of ions are taking place. Both the reactants must be present in aqueous state to react.

Answer 2

The following reaction will takes place:

$\sf{BaCl_2+Na_2SO_4 \rightarrow BaSO_4+NaCl}$

$\sf{BaCl_2\:=\:Ba^{2+}+Cl^{-}}$

$\sf{Na_2SO_4\:=\:Na^{+}+SO_{4}^{2-}}$

Here, positively charged ions are called Cation and negatively charged ions are called Anions.

A cation $\sf{Ba^{2+}}$ reacts with $\sf{SO_4^{2-}}$ anion. Similarly, $\sf{Cl^{-}}$ which is a anion reacts with a cation $\sf{Na^{+}}$ and forms products like $\sf{BaSO_4}$ which is a white precipitate and $\sf{NaCl}$

Balance Reaction:

$\sf{BaCl_2(aq)+Na_2SO_4(aq) \rightarrow BaSO_4(s)+2NaCl(aq)}$

When Barium Chloride reacts with Sodium Sulphate solution, exchange of ions takes place and Barium Sulphate (white ppt.) and Sodium Chloride are formed as a product. The above reaction is an example of Double Displacement Reaction.
