EDTA Titration of Ca2+ and Mg2+ in Bottled Water
Course material - 4 pages - Physics
The objective of this experiment is to determine the total concentration of metal ions required to completely react with EDTA, or ethylene diamine tetra-acetate. The concentration determined will then be taken as the equivalent concentration of Ca2+ and Mg2+. Ca2+ will be analyzed separately in...
Ferromagnetism and the Curie-Weiss Law
Course material - 3 pages - Physics
In "Ferromagnetism and the Curie-Weiss Law" the author will start by giving a more complete derivation of the Curie-Weiss law, which might make a few points clearer. Then he will try to address some of your questions more directly. The author hopes that the derivation itself will make things...
Position of the Fermi Level for Extrinsic Semiconductors: Additional Notes for Solid State Physics
Course material - 2 pages - Physics
In "Position of the Fermi Level for Extrinsic Semiconductors" the author will talk a little more in detail about doped semiconductors. Here, the author answers the following questions: (i) What is the position of the Fermi level for an extrinsic semiconductor? (ii) What is the concentration of...
