Comparison of external standards, internal standards and standard addition method. For students of analytical chemistry and instrumental analysis.

This is a very basic video about the basic logical concept that underlies dilutions. This gives a very fundamental explanation of where the equation M1*V1 = M2* V2

Conceptual explanation of the way a Quadrupole Mass Filter works.

For students of environmental chemistry, geochemistry, limnology etc. who are learning about the DOC analysis. This video gives a basic (simplified) overview of how the DOC analysis typically works. The process described is as is carried out on a certain type of Shimadzu TOC analyzer.

For general chemistry students at high school and freshman (first year) college level. An introduction to energy considerations in ionic bonding and the Born-Haber cycle.

For general chemistry students at high school or freshman (first year) level. An overview of the three main types of bonds, which are classified according to the wave valence electrons in the bonded atoms behave.

This is a webcast of a sophomore (or second year) Analytical Chemistry lecture that was delivered by Dr. David Kreller of Georgia Southern University (Chemistry Department) on June 14, 2012. The lecture covers basic aspects of electromagnetic radiation and then goes on to cover basic principles of adsorption and the Beer-Lambert law.

For students of analytical chemistry (quantitative analysis). This video works through a sample calcuation that uses the Nernst equation. The video also shows where the equation comes from, in terms of basic chemistry/electrochemistry theory.

I provide an introduction to VSEPR theory, to help students of general chemistry learn about the theoretical ideas that underlie molecular geometries.

An introduction to the A-X-E system of notation that is very helpful to people who are using the concepts of Valence Shell Electron Pair Repulsion Theory to understand the fundamental set of basic molecular geometries.

This video explains several concepts that underlie acid-base titrations. Terms defined include titrant, titrand, equivalent, normality, equivalence point, end point, titration error, direct titration, back titration, primary standard, standardization.
