From a list of almost 2000 names and formulas, students will be given the opportunity to practice their ability to name ionic compounds, given the formula, and determine the formula given the name.
Manganese(IV)containing oxides are effective catalysts for oxidation of watersoluble cyanide over a wide pH range () and temperature (15°250° C.). Oxygen is the preferred oxidizing agent at partial pressures between about and 5 atmospheres ( psi, 20517 kPa). Electrolytically deposited MnO 2 is one preferred form of the catalyst.
