Determination of Percent Potassium & Percent Iron in an Iron Oxalate Salt by Ion Exchange Introduction: This experiment involves determining both the percent potassium (K) and iron (Fe) in a single titration after passing a solution containing a known mass of complex salt through an ion exchange column. Ion Exchange: Certain materials called ion exchange resins consist of rather large molecules which contain ions that can be displaced. The resins are solids‚ insoluble in water‚ usually granular

Ion Exchange Chromatography Discussion: The first exercise preformed in this lab was ion exchange chromatography. The purpose of this experiment is to separate molecules based on their differences in charge. Since it is based on charge the amino acids in the cation exchange column‚ if negatively charged‚ flow through the column first because they don’t want to bind to the sodium ions. The positively charged ions will elute last at the highest ph because they bind to the negatively charged beads

Importance of Calcium Ions Alyssa Foels 12 February 2015 Kilfe Calcium is a cation‚ a positively charged atom‚ and it is essential to all living things. It was first discovered in 1808 by Humphrey Davy. When forming an ionic bond with other elements‚ calcium loses electrons to make its valence shell stable. This means that it has more protons than electrons‚ making it have a slight positive charge (Calcium). Calcium has many roles and functions in the human body. Calcium ions are the most abundant

Uranium (U) is a metallic‚ silver-gray element that is a member of the actinide series. It is the principle fuel for nuclear reactors‚ but it also is utilized in the production of nuclear weapons. Because uranium is radioactive‚ it is constantly emitting particles and changing into other elements‚ like thorium. Uranium has a well-established radioactive decay chain. U-238 and U-235 (which has 143 neutrons) are the most common isotopes of uranium. Uranium naturally includes all three isotopes (U-238

entire organism. Bones are constantly breaking down and rebuilding‚ and calcium is directly involved in this process. Calcium ions (Ca2+) are essential mediators of a wide variety of cellular activities‚ including the passing of information along neurons and between adjacent neurons. Hormonal regulation is also mediated by the proper functions of calcium and calcium ions in the body. Considering all of the roles that it plays‚ calcium is of the upmost physiological importance and is the most abundant

Steven‚ I think firearms identification is quite fascinating and intriguing as well. I too‚ own several firearms and find them to be empowering to say the least. What is more amazing to me is how the markings on a bullet are as specific to a weapon as fingerprints are to a person. Just like fingerprints of an individual each bullets marking are as unique and identifiable as the gun it was projected from. Yet‚ alterations can be made to such markings as a result of the things a bullet may pass through
