when sodium sulphate solution reacts with barium chloride solution the solution after the reaction contains mainly--------

Answer 1

na2(so4)+bacl2----- baso4+2nacl

Answer 2

When ‘sodium sulphate solution’ reacts with ‘barium chloride solution’ the solution after the reaction contains mainly sodium chloride.

Explanation:  

• Sodium sulphate reacts with the ‘solution of barium chloride’ resulting in double displacement reaction in which the ions are exchanged.  

• Hence ‘barium sulfate and sodium chloride’ are formed. Now the solution in water consists of only sodium chloride.

• This is because sodium chloride dissolves in water barium sulfate does not dissolve in water. It settles down and the precipitate hence formed is whitish in colour. The reaction is  

           $\bold{\mathrm{Na}_{2} \mathrm{SO}_{4}+\mathrm{BaCl}_{2} \rightarrow \mathrm{NaCl}+\mathrm{BaSO}_{4}}$
