Importance of Reducing and Oxidizing Agents
Reducing agents and oxidizing agents are the ones responsible for corrosion, which is the “degradation of metals as a result of electrochemical activity”. Corrosion requires an anode and cathode to take place. The anode is an element that loses electrons (reducing agent), thus oxidation always occurs in the anode, and the cathode is an element that gains electrons (oxidizing agent), thus reduction always occurs in the cathode. Corrosion occurs whenever there’s a difference in oxidation potential. When this is present, the anode metal begins deteriorating, given there is an electrical connection and the presence of an electrolyte.

“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
“The child thinks of growing old as an almost obscene calamity, which for some mysterious reason will never happen to itself. All who have passed the age of thirty are joyless grotesques, endlessly fussing about things of no importance and staying alive without, so far as the child can see, having anything to live for. Only child life is real life.”
—George Orwell (1903–1950)
“Single acts of tyranny may be ascribed to the accidental opinion of a day; but a series of oppressions ... too plainly prove a deliberate, systematical plan of reducing us to slavery.”
—Thomas Jefferson (1743–1826)
“Modern man’s capacity for destruction is quixotic evidence of humanity’s capacity for reconstruction. The powerful technological agents we have unleashed against the environment include many of the agents we require for its reconstruction.”
—George F. Will (b. 1941)
