Solutions. are defined as homogeneous mixtures of two or more pure substances.. The . solvent. Redox. ) Reactions. Chapter 20. Salt on icy roads can make driving safer, but the salt that clings to the metallic parts of cars can cause them to corrode or rust relatively quickly. This corrosion is one example of a chemical reaction called oxidation-reduction. You will learn about oxidation-reduction reactions.. Flight Experiment, Mission 5 to ISS. TEAM DEFYING MICROGRAVITY.

OXIDATION AND REDUCTION. ESSENTIAL IDEA. Redox (reduction-oxidation) reactions play a key role in many chemical and biochemical processes.. NATURE OF SCIENCE (1.9). How evidence is used – changes in the definition of oxidation and reduction from one involving specific elements (oxygen and hydrogen), to one involving electron transfer, to one invoking oxidation numbers is a good example of the way that scientists broaden similarities to general principles..
