which term best describes cl in the following reaction?
2nh₃ + (ocl)⁻ → n₂h₄ + h₂o + cl⁻
a) reducing agent
b) oxidized
c) electrolyte
d) reduced

Explanation:

To determine the term for Cl, we analyze its oxidation state. In \((\text{OCl})^-\), let the oxidation state of Cl be \(x\). Oxygen is -2, so \(-2 + x = -1\) gives \(x = +1\). In \(\text{Cl}^-\), the oxidation state is -1. A decrease in oxidation state means reduction. So Cl is reduced.

• Option A: Reducing agent is oxidized, Cl is reduced, so A is wrong.
• Option B: Oxidized means oxidation state increases, but Cl's state decreases, so B is wrong.
• Option C: Electrolyte is a substance that conducts electricity in solution, not related here, so C is wrong.
• Option D: Cl's oxidation state decreases (from +1 to -1), so it is reduced.

Answer:

D) Reduced
