What is transferred between reactants during a double decomposition reaction?
A
Molecule
B
Atom
C
Electron
D
Ion
Correct Option:
D
Explanation
In a double decomposition or double displacement reaction, the reacting compounds exchange their ions. For example, AgNO₃ + NaCl → AgCl + NaNO₃. The silver and sodium ions effectively exchange their ionic partners. There is no transfer of electrons of the type characteristic of a redox reaction.
