Solution

The correct option is A True

The reaction of $N a C l$ and $C a C O_{3}$ gives sodium carbonate. But this reaction cannot be used for the manufacture of washing soda since it is a reversible reaction.

$2 N a C l + C a C O_{3} ⇌ N a_{2} C O_{3} + C a C l_{2}$ .
Hence the given statement is True.
