How to Calculate Oxidation Numbers Introduction
 
13:26
We'll learn how to determine the oxidation numbers or oxidation states for a the elements in a chemical compound. The oxidation numbers tell us how electrons are divided up or shared between atoms in a chemical compound. The oxidation numbers also tell us how electrons move in an oxidation reduction (redox) reaction. There are a set a rules that we use to determine oxidation number. Group 1A elements (alkalai metals) always have an oxidation of +1. Group 2A elements (alkaline earth metals) always have an oxidation number of +2. Elements on their own have an oxidation number of 0, and monatomic ions have an oxidation number that is equal to the ionic charge.

How to assign oxidation numbers to the atoms in a molecule. 1. Elements have oxidation number = 0 2. Hydrogen's always +1 (except in "hydrides") 3. Oxygen's always -2 (except in "peroxides") 4. Other atoms get the charge they prefer, as long as the sum of oxidation numbers for all atoms = the total charge on the atom.

How To Calculate Oxidation Numbers - Basic Introduction
 
31:15
This chemistry video tutorial provides a basic introduction on how to calculate oxidation numbers. It discusses how to find the oxidation states of elements such as Zn, O2, F2, and P4 and how to find the oxidation numbers of polyatomic ions such as SO4 2-, PO4 3-, NO3-, ClO4-, Hg2+2, O2-2 and so forth. Examples include transition metals found in ionic compounds such as Fe3O4, V2O5, and K2CrO4. In addition, this video explains what's behind a fractional oxidation state. For instance, the oxidation number of Fe in Fe3O4 is a fraction +8/3. This tutorial relates oxidation states to electronegativity and positive and negative partial charges. Practice problems include OF2, HCl, NaH, BH3, H2S, SO2, NH3, NO2, CH4, and CO2. This video covers all of the rules relating to oxidation numbers. For instance, Hydrogen usually has a +1 oxidation state when bounded to a nonmetal but it tends to have a -1 oxidation number when attached to a metal.

Introduction to Oxidation Reduction (Redox) Reactions
 
13:05
This is an introduction to oxidation reduction reactions, which are often called redox reactions for short. An oxidation reduction (redox) reaction happens when electrons are transferred between atoms. A loss of electrons is called oxidation, and we say that atom has become oxidized. A gain of electrons is called reduction, and we say that the atoms has become reduced. The two separate parts (oxidation and reduction) of an oxidation reduction (redox) reaction are called half reactions. Two half reactions can be put together to make the whole reaction. Oxidation numbers are numbers that can be written above atoms to show whether they are gaining or losing electrons.

Redox Reactions: Crash Course Chemistry #10
 
11:13
All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemistry, which contains the majority of chemical reactions. As electrons jump from atom to atom, they carry energy with them, and that transfer of energy is what makes all life on earth possible. **Special Thanks to Matt Young at the University of Montana (Geosciences Department, Environmental Biogeochemistry Lab) who helped with the chemical demonstrations.** Oxidation 1:42 Reduction 1:03 Oxidation Numbers 3:29 Redox Reactions 5:59 Oxidation Reactions 6:28 Balancing Oxidation Reactions 7:18 Also thank you to the following chemistry teachers for assistance: James Sarbinoff Rachel Wentz Edi González Lucas Moore Chris Conley Addie Clark Julia Rosinski Want to find Crash Course elsewhere on the internet?

Redox Reactions
 
11:41
031 - Redox Reactions In this video Paul Andersen explains how redox reactions are driven by the movement of electrons from the substance that is oxidized to the substance that is reduced. Oxidation is the loss of electrons and reduction is the gaining of electrons. Since electrons are not normally displayed in a chemical equation oxidation numbers are important in determining what atom is oxidize and what atom is reduced. Redox reactions are important in energy production and can also be used in basic titrations. Do you speak another language?

Complex Ions, Ligands, & Coordination Compounds, Basic Introduction   Chemistry
 
13:42
This chemistry video tutorial provides a basic introduction into complex ions, ligands, and coordination compounds. A complex ion typically consist of a transition metal cation bounded to ligands which can be neutral molecules or ions. The number of ligands attached to the transition metal ion is known as the coordination number. This video explains how to determine the oxidation state of the transition metal ion in a complex ion and within a coordination compound. A coordination compound consist of a complex ion and a counterion. The counterion may be a cation or an anion. This video briefly discusses werner's theory of coordination compounds and the concept of primary valence and secondary valence as it relates to the transition metal ions in complex ions.
