Question
Chapter 18, Problem 4ALQ
Interpretation Introduction
Interpretation:
The true statements amongst the given are to be selected about oxidation and reduction process.
Concept Introduction:
The oxidation and reduction are defined by the loss and addition of electrons. The loss of electrons results in oxidation whereas addition of electrons results in reduction. The oxidation and reduction process complementary to each other.
