In whic of the following types of reaction is there an exchange of ions between the reactants?
Double displacement reaction
The correct answer is option 3 I.e. Double displacement reaction .
In a double displacement reaction, there is an exchange of ions between the reactants.
These reactions generally occur between two ionic compounds in solution, and they often result in the formation of a precipitate, gas, or water.
Example: Na2SO4+BaCl2→BaSO4↓+2NaCl
Here, Na⁺ and Ba²⁺ swap places — a classic double displacement!
