Quantitative Chemical Analysis
... One of our most pressing problems is the need for sources of energy to replace oil. The chart at the right shows that world production of oil per capita has probably already peaked. Oil will play a decreasing role as an energy source and should be more valuable as a raw material than as a fuel. Ther ...

To name an ionic compound, one should name the cation first, and then name the anion (with the word ‘ion’ omitted). It is not necessary to indicate the number of cations and anions in the compound because it ...

Highly polar molecules interact fairly strongly with the polar SiOH groups at the surface of these adsorbents, and will tend to stick or adsorb onto the fine particles of the adsorbent while weakly polar molecules are held less tightly. Weakly polar molecules generally tend to move through the adsor ...

Ion chromatography
Ion-exchange chromatography (or ion chromatography) is a process that allows the separation of ions and polar molecules based on their affinity to the ion exchanger. It can be used for almost any kind of charged molecule including large proteins, small nucleotides and amino acids. It is often used in protein purification, water analysis, and quality control.
