Solution

In a complexometric titration, the complexing agent is typically a Lewis base, which is an electron donor. This is because a complexing agent needs to be able to donate electrons to the metal ion to form a complex ion. Therefore, the correct answer is a. Electron Donor or Lewis's Base.

Here's a step-by-step explanation:

  1. In a complexometric titration, a complex ion is formed when a metal ion reacts with a molecule or ion that can donate a pair of non-bonding electrons.

  2. The molecule or ion that donates the electrons is called a ligand or complexing agent.

  3. According to Lewis acid-base theory, a Lewis base is a species that can donate a pair of non-bonding electrons.

  4. Therefore, in a complexometric titration, the complexing agent is a Lewis base, or an electron donor.

  5. So, the correct answer is a. Electron Donor or Lewis's Base.
