What are Surface Chemistry and Redox Reaction?

Surface Chemistry deals with the study of chemical reactions that occur at the interface of two phases, such as solid-liquid or solid-gas. It helps in understanding phenomena like adsorption, catalysis, and colloidal systems.

Redox Reactions, short for reduction-oxidation reactions, involve the transfer of electrons between substances. In these reactions, one substance loses electrons (oxidation), while another gains electrons (reduction).
