Question
**Question:** According to the table of standard reduction potentials, what is the best reducing agent among the following given species? - ○ Pb - ○ Mg^+2 - ○ Ag^+ - ○ Ag - ○ H_2 **Explanation:** This multiple-choice question asks students to identify the best reducing agent based on standard reduction potentials, which are measurements of the tendency of a chemical species to be reduced (gain electrons). The species listed are: lead (Pb), magnesium ion (Mg^+2), silver ion (Ag^+), silver (Ag), and hydrogen (H_2). To solve this question, students need to refer to a standard table of reduction potentials and pick the species with the lowest (most negative) standard electrode potential, as this indicates the strongest reducing capability.

Expert Solution
Step 1

Reducing agent: a reducing agent is defined as a substance which is used to donate electrons to attain oxidised form. 

Strong reducing agent: higher the ability to donate electrons, stronger will be the reducing agent.
