In respect to this, how do you identify oxidizing and reducing agents?

A reducing agent is a substance that causes another substance to reduce. So to identify an oxidizing agent, simply look at the oxidation number of an atom before and after the reaction. If the oxidation number is greater in the product, then it lost electrons and the substance was oxidized.

Secondly, which elements are good reducing agents? Good reducing agents include the active metals, such as sodium, magnesium, aluminum, and zinc, which have relatively small ionization energies and low electro-negativities. Metal hydrides, such as NaH, CaH₂, and LiAlH₄, which formally contain the H^- ion, are also good reducing agents.

In respect to this, how do you find the weakest reducing agent?

Explanation: Here's a typical table of standard reduction potentials. The species at the top left have the greatest "potential" to be reduced, so they are the strongest oxidizing agents. The strongest oxidizing agent in the list is F2 , followed by H2O2 , and so on down to the weakest oxidizing agent, Li+ .

Is HCl a strong reducing agent?

HCl (Cl^-) can be oxidized to chlorine gas (Deacon reaction) using a stronger oxidizing agent than HCl (TiO2). HCl (H^+) can be reduced to hydrogen gas via a weaker oxidizing agent than HCl (stronger reducing agent) such as Zn. There is no ultimate oxidizing agent or reducing agent.
