Question

In an acid solution using the half-reaction method balance the following oxidation/reduction reactions. Identify the oxidizing agent and the reducing agent in each reaction. a. ??(?) + ??3 −(??) → ?? 2+(??) + ??(?) b. ??2?7 2−(??) + ?? −(??) → ?? 3+(??) + ??2 (?) c. ??2 2+(??) + ??(?) → ? 4+(??) + ???4 2− d. ??2 (??) → ???3 −(??) + ?? −(??)

This was how the question was given.

Answer 1

Oxidizing agents cause oxidation in another substance and gains electrons in the chemical reaction. Therefore, its oxidation state decreases.

A reducing agents reduces other substances and loses electrons. Therefore its oxidation state increases.

In order to find out the oxidizing agent and the reducing agent in the given reaction, we will compare the oxidation agent in the given reaction, we will compare the oxidation state of different atoms.

Here, so playing both roles. One molecules is oxidizing another molecules of cl.
