Question

In which type of reaction can two compounds exchange ions to form two different compounds?

Answer 1

Double-replacement reaction

Answer 2

Explanation:

A reaction in which two compounds exchange ions to form two different compounds is known as a double displacement reaction.

For example, $AgNO_{3}(aq) + NaCl(aq) \rightarrow AgCl(ppt) + NaNO_{3}$

Since, two ions get exchanged in this type of reaction, that is why, it is known as double displacement reaction.
