Question

Solutions of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride. (Write a balanced chemical equation with state symbols for the given reactions.)

Answer 1

We have been given a chemical equation to solve.

We have been given the equation in words and we need to use the appropriate compound symbols and name and complete the balanced equation.

The question given to us is, whether barium chloridemixed with sodium sulphate in water have a reaction together to produce insoluble barium sulphate and the subsequent solution that is produced is  of sodium chloride.

The balanced chemical equation is Bacl2+Na2SO4 --> BaSO4 + 2NaCl

Answer 2

Answer:

A white ppt. ( precipitate ) is formed.

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

Doubled Displacement reaction
