Answer

Brief Explanations:

In a double - replacement reaction, the positive and negative ions of two ionic compounds exchange places. For example, in the reaction between silver nitrate ($AgNO_3$) and sodium chloride ($NaCl$), the silver ion ($Ag^+$) and sodium ion ($Na^+$) exchange anions, resulting in the formation of silver chloride ($AgCl$) and sodium nitrate ($NaNO_3$). It is not a substitution (single - replacement is substitution), not about losing atoms of a compound, and not about electron exchange between atoms (that's redox).

Answer:

ions are exchanged between two compounds.
