Answer

Brief Explanations:

Reduction is the gain of electrons. In the given equations, the equation $2Cl + 2e^-\longrightarrow 2Cl^-$ shows chlorine atoms gaining electrons to form chloride ions. The other equations represent oxidation (loss of electrons).

Answer:

$2Cl + 2e^-\longrightarrow 2Cl^-$
