In a double-displacement reaction, the cations and anions switch places to produce the product. The ions swap their place to yield new compounds. Thus, option B is correct.
What is a double-displacement reaction?
A double-displacement reaction, also called salt metathesis reaction is a process involving the exchange of the bonds and the positive and the negative ions to result in compounds different from the reactant.
The positively charged cation and the negatively charged anion swap their places and produce new products or compounds. It can be of three types namely neutralization, precipitation, and gas formation.
Therefore, the ions (cations and anions) switch their places in a double-displacement reaction.
