Q: In the electrochemical series, which element is the best reducing agent? (2022)

Solution: Li is the best reducing agent among the given alkali metals due to its low ionization energy.

Steps: 7

Step 1: Understand what a reducing agent is. A reducing agent is a substance that donates electrons to another substance, reducing it while itself getting oxidized.
Step 2: Look at the electrochemical series, which lists elements based on their ability to lose electrons.
Step 3: Identify the alkali metals in the series. These include lithium (Li), sodium (Na), potassium (K), etc.
Step 4: Compare the ionization energies of these alkali metals. Ionization energy is the energy required to remove an electron from an atom.
Step 5: Recognize that lower ionization energy means it is easier for the element to lose an electron and act as a reducing agent.
Step 6: Note that lithium (Li) has the lowest ionization energy among the alkali metals.
Step 7: Conclude that since Li has the lowest ionization energy, it is the best reducing agent among the alkali metals.
