. In each of the following reactions, identify which species is the oxidizing agent.

a. 2Al ( s ) + 6HCI ( a q ) 2AlCl 3 ( a q ) + 3H 2 ( g )    b. Cu ( s ) + H 2 SO 4 ( a q ) CuSO 4 ( a q ) + H 2 ( g )

Interpretation Introduction

(a)

Interpretation:

The oxidizing agent should be identified.

Concept Introduction:

The oxidation-reduction reaction is also known as a redox reaction. In this reaction, one reactant is oxidized and other is reduced. The balancing of oxidation-reduction reaction can be done by simple method by comparing the number of each atoms on both sides of the reaction arrow without addition of hydrogen ion, water molecule and electrons from outside.

Explanation

The given reaction is as follows:

2Als+6HClaq2AlCl3aq+3H2
