Question

In a double displacement reaction, how many reactants exchange their respective ions to form new products?

• A. 2

Answer 1

The correct option is A 2
The reaction in which exchange of ions takes place between the two reactants to form new products is called a double displacement reaction.

For example: ${\text{AgNO}}_3\text{(aq)}+\text{NaCl(aq)}\to \text{AgCl}\text{(s)}+{\text{NaNO}}_3\text{(aq)}$

The reaction between silver nitrate and sodium chloride involves exchange of their ionic counter parts to form the product.
