Question

question 2 (2 points)
in the reaction below, the reactant aluminum __________ electrons and is the ___________________ agent.
al (s) + 3 ag⁺ (aq) → al³⁺ (aq) + ag (s)
○ loses; reducing
○ loses; oxidizing
○ gains; reducing
○ gains; oxidizing

Explanation:

Oxidation is the loss of electrons. In the reaction, aluminum goes from an oxidation state of 0 in Al(s) to +3 in Al³⁺(aq), so it loses electrons. A reducing agent is a substance that donates electrons and gets oxidized in a redox - reaction. Since aluminum loses electrons and gets oxidized, it is the reducing agent.

Answer:

A. loses; reducing
