Nomenclature - Purdue University

The ClO 4-ion is therefore the perchlorate ion. There are only a handful of exceptions to these generalizations. The names of the hydroxide (OH - ), cyanide (CN - ), and peroxide (O 2 2- ) ions, for example, have the -ide ending because they were once thought to be monatomic ions.

Drying agents - University of California, Los Angeles

21/3/2016· Calcium sulfate (n=0.5, e=0.004 mg/L) is a neutral and good drying agent. However, it does not have a high capacity, which makes it useless for very wet solutions. The commercially available Drierite® contains about 2 % cobalt chloride as indior, which can be leached out into various solvents i.e. ethanol, DMSO, DMF, ethers, etc. Drierite is often used in desicors .

Water Hardness - Department of Chemistry

Ion-exchange devices consist of a bed of plastic (polymer) beads covalently bound to anion groups, such as -COO-. The negative charge of these anions is balanced by Na + ions attached to them. When water containing Ca 2+ and Mg 2+ is passed through the ion exchanger, the Ca 2+ and Mg 2+ ions are more attracted to the anion groups than the Na + ions.

Zinc - Wikipedia

Zinc is a slightly brittle metal at room temperature and has a silvery-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table . In some respects, zinc is chemically similar to magnesium : both elements exhibit only one normal oxidation state (+2), and the Zn 2+ and Mg 2+ ions are of similar size.
