Question

The role of a reducing agent in metallic nanomaterials synthesis is to?

• A. Act as a solvent for the reaction
• B. Donate electrons to the metal ions
• C. Accept electrons from the metal ions
• D. Increase the temperature of the reaction mixture

Hint:

In redox reactions, remember that the reducing agent donates electrons and is itself oxidized in the process. It's important in processes like the synthesis of metallic nanoparticles.

Answer 1

The Correct Option is B

A reducing agent is a substance that donates electrons to another substance, thus reducing the oxidation state of the other substance. In metallic nanomaterials synthesis, the reducing agent typically donates electrons to the metal ions, causing them to be reduced to their elemental metallic form.
Thus, the correct role of the reducing agent is to donate electrons to the metal ions, facilitating their conversion from metal cations to metallic nanoparticles.
