Problem 6.1: What is the difference between transactional
From Chapter 6 Problem Set. Level 1: Conceptual Mastery.
Question
What is the difference between transactional oxidation and destructive oxidation? Why is the formation of NaCl considered transactional while the rusting of iron is destructive?
Answer
Show answer
Transactional oxidation transfers electrons without destroying a useful structure. Sodium and chlorine exchange electrons to form a stable salt, but no engineered material or living structure has lost its function. Destructive oxidation strips electrons from a working material, forcing it into a new and less useful form. Rusting converts iron metal into iron oxide; the pipe wall does not spontaneously rebuild itself under normal system conditions.
