Question

2na → na⁺ + e⁻ is a reducing agent equation, and it depicts the oxidation of ______.

○ iron

○ sodium

Explanation:

The given equation is \( 2[\text{Na}
ightarrow \text{Na}^+ + \text{e}^-] \). In this oxidation - reduction (redox) reaction, the species that is being oxidized is the one that loses electrons. Here, sodium (Na) is losing an electron to form sodium ion (\( \text{Na}^+ \)). Iron is not involved in this equation at all. So the equation depicts the oxidation of sodium.

Answer:

sodium (the option with text "sodium")
