Question

Write a balanced chemical equation with state symbols for the chemical reaction that takes place when solutions of barium chloride and sodium sulphate react to give insoluble barium sulphate and the solution of sodium chloride.

Answer 1

• The skeleton equation for the given reaction is represented as:
  ${\mathrm{Na}}_2{\mathrm{SO}}_4+{\mathrm{BaCl}}_2\to {\mathrm{BaSO}}_4+\mathrm{NaCl}$

• Balanced chemical equation with the state is represented as:
  ${\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+{\mathrm{BaCl}}_2\left(\mathrm{aq}\right)\to {\mathrm{BaSO}}_4\left(s\right)+2\mathrm{NaCl}\left(\mathrm{aq}\right)$
