PPT-REDOX & OXIDATION NUMBERS

REDOX REACTIONS OILRIG O xidation I s L oss of electrons R eduction I s g ain of electrons This is really important Think of January sales OXIDATION NUMBER RULES Oxidation numbers which are assigned to ions of each element in a compound help us to write half equations and full ionic equations. Databases treating redox reactions must include either . O. 2. (. aq. ). or . H. 2. (. aq. ). in the list of Basis Species. . This species is the database’s “redox pivot”.. O. 2. (. aq. ) is the . Definition. If oxidation occurs, then reduction must also occur. Any chemical process in which elements undergo a change in oxidation number is a . Redox reaction. Example. 2Na + Cl. 2. . → 2Na. 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.. Lecture 9. Law of Mass Action. Important to remember our equation. describes the . equilibrium. condition. At non-equilibrium conditions it is called the . reaction quotient, Q. .. Written for the reaction H. REDOX PROCESSES. 9.1. 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.. Aka REDOX reactions. Electrochemistry. The study of chemical reactions involving the transfer of electrons between reactants. . Oxidation. Loss of electrons. happens at the anode. Reduction. gain of electrons. 1.2.3: Redox explains the chemistry behind batteries and electroplating precious metals onto strong base metals. It also explains how to break apart water into hydrogen and oxygen, and lots more.. 4: These 2 reactions are always paired and balanced.. Organic matter generated with photosynthesis. Organic matter decomposes (. remineralized. ) during respiration. Photosynthesis. Reaction that converts CO. 2. plus nutrients (N, P, other micronutrients) to organic matter and oxygen.

Oxidation-Reduction (Redox) Reactions. Redox reactions involve an electron transfer.. These reaction occur between metals and nonmetals.. Ionic reactions are redox reactions.. The name. Define electrochemistry and a number of important associated items. Split redox reactions into their oxidation & reduction half-equations. Produce balanced redox equations for reactions in acidic solutions. 4.2: Classifying chemical reactions. Define three common chemical reaction types: . (1) precipitation; (2) neutralization; (3) redox. Classify reactions given a balanced chemical equation. Identify common acids & bases.
