By thoroughly stirring, 5 g boric acid and 100 ml hydroxyl silicone oil were mixed evenly in a ceramic dish. Then, the mixture was heated at 180 C for 1.5 h and was stirred every 15 min to ensure the homoge-neous reaction. The mixture formed cross
History of chemistry - Wikipedia
The history of chemistry represents a time span from ancient history to the present. By 1000 BC, civilizations used technologies that would eventually form the basis of the various branches of chemistry. Examples include the discovery of fire, extracting metals from ores, making pottery and glazes, fermenting beer and wine, extracting chemicals from plants for medicine and perfume, rendering

Flame Colors - Georgia State University
Though not as definitive as the spectral fingerprints from atomic spectra, the colors produced by chemicals when inserted into a flame can be used to identify some constituents of minerals. One procedure used was to put a small amount of the chemical on a small loop of platinum wire and place it into the open flame from a laboratory burner.

Nickel sulfamate plating bath pH is dropping/decreasing
12/7/2010· Boric Acid in the solution ionizes to produce Hydrogen ions to compensate for the removal of Hydrogen ions, thus acting as a buffer. If the pH is falling, most likely (unless acid is entering the solution from an outside source) the anode is not dissolving properly and Hydroxyl (OH-) ions are being discharged at the anode.
