Trihydrogen

The parent acid of the hexakiscyanoferrate(3—) salts is ferricyanic acid [17126464] (trihydrogen hexakiscyanoferrate). Red-brown needles are obtained by evaporation of solutions prepared by adding sulfuric acid to tribarium bis(hexakiscyanoferrate). The acid is used to prevent metal surface corrosion. 

Dithiocarbamates are almost quantitatively converted into trifluorometh-ylamines by reacting at ambient temperature with either tetrabutylammonium dihydrogen trifluoride, triethylamine trihydrogen trifluoridc, or pyridinium polyhydrogen fluoride and an 7V-halo imide reagent [75] (equation 19)...

A TRIRETICULATE CRYSTAL STRUCTURE TRIHYDROGEN COBALTICYANIDE AND TRISILVER COBALTICYANIDE ... 

Summary.—The crystals trisilver cobalticyanide and trihydrogen cobalticyanide have been shown to have a trireticulate structure, with nearly regular cobalticyanide octahedra connected by nitrogen-silver-nitrogen bonds or by hydrogen bonds between the nitrogen atoms. 

The electrolysis is carried out on a solution of the organosilane (2 mmol) in acetonitrile in the presence of tetraethylammonium trihydrogen tetrafluoride (1 mol Lr ) with platinum electrodes under the condition of a constant potential of 2.3 V (vs Ag/AgNO, 0.1 mol). A divided cell is used and the electrolysis is continued until 115.78 kC - mol 1 have been passed. The electrolyte is extracted with pentane. The products are given in Table 2. 

Common names of chemical compounds are generally much shorter than the corresponding systematic names. The systematic names for water, ammonia, and methane, for example, are dihydrogen monoxide, H20 trihydrogen nitride, NH3 and tetrahydrogen carbide, CH4. For these compounds, which would you rather use common names or systematic names ... 

SOaH group may be introduced in certain cases by the use of potassium trihydrogen disulphate, KH SO, or sodium pyrosulphate, Na2S207.

Sodium periodate, and less frequently potassium periodate, are employed in oxidations which are to be carried out within the pH range 3-5. Sodium metaperiodate (NaI04) has a solubility in water of c. 0.07 g per ml the addition of alkali leads to the precipitation of the far less soluble sodium paraperiodate (Na2H3I06, disodium trihydrogen orthoperiodate, water solubility c. 0.20%). Sodium paraperiodate is available commercially and may be converted into the...
