What can be inferred from the following equation?
(i) It is a double displacement reaction.
(ii) It is a precipitation reaction.
(iii) It is a decomposition reaction.
(iv) BaSO4 is soluble in water
(v) BaSO4 is precipitate.
(vi) NaCl dissolves in water.
(i),(ii), (v), (vi).
In above reaction, Na+ and Ba2+ ions are exchanged between the reactants, hence it is a displacement reaction.
The product BaSO4 is not soluble in water, hence is a precipitate. This reaction is also called precipitation reaction due to the formation of a precipitate. NaCl dissolves in water.
