Reactions in which there is an exchange of ions between the reactants are called?
Reactions in which there is an exchange of ions between the reactants are called?
Solution
✅ Correct Option: 3
When two compounds swap their ions to form two new compounds, the reaction is a double displacement, as in sodium sulphate reacting with barium chloride to give barium sulphate and sodium chloride. A single displacement involves only one more reactive element replacing another, and decomposition splits one compound into simpler products.
