A colourless solution is formed, consisting of strongly alkalic sodium hydroxide (caustic soda) and hydrogen gas. This is an exothermic reaction. Sodium metal is heated and may ignite and burn with a characteristic orange flame. Hydrogen gas released during the burning process reacts strongly with...

Sodium is used to produce sodamide from reaction with ammonia and to reduce TiCl 4 , ZrCl 4 , and KCl to Ti, Zr, and K, respectively. An alloy of Na and K is used in nuclear reactors as a heat transfer agent. Several sodium compounds are economically important. NaCl (ordinary salt...
In the synthesis process, 100 g of 6 mm agate spheres and 1 g of biomass feedstock were added to agate jars. Each jar was filled with 20 ml of sulfuric acid, sodium hydroxide, or deionized water (control). The jars were subjected to a 12-h ball-milling process at 300 rpm in ...
After that, the demulsification rate (i.e., oil and/or water separation) was monitored until a complete separation is attained. Additionally, the ability to switch the crude O/W nanoemulsions by increasing their pH instead of decreasing it was also examined using sodium hydroxide (NaOH), ...
Iron(III) chloride (FeCl3‧6H2O, Alfa Aesar, ≥98%), sodium hydroxide (NaOH, Alfa Aesar, 98%), sodium sulfate (Na2SO4, Sigma Aldrich, ACS reagent, ≥99%), tetrakis(dimethylamino)titanium (TDMAT), hydrogen peroxide (H2O2, Sigma Aldrich, 30%), 2,4-Dichlorophenoxyacetic acid (2,4D...
At low sodium vapour pressure ( 1×10 -3 mbar) the water cluster pick up more than 50 Na atoms and reaction products Na(NaOH) n ( n = 2, 4...50) dominate the mass spectra. The even number of NaOH units in the products indicate that also in a finite cluster the reaction occurs ...
To a magnetically stirred dichloromethane solution (1.5 ml) of o-tolunitrile (0.5 g, 4.27 mmol) cooled in anice bath, are added 30% hydrogen peroxide (2.0 ml), tetrabutylammonium hydrogen sulfate(0.290 g, 0.85 mmol), and a 20% aqueous solution of sodium hydroxide (1.6 ml). Thereaction mi...
Water and its interactions with metals are closely bound up with human life, and the reactivity of metal clusters with water is of fundamental importance for the understanding of hydrogen generation. Here a prominent hydrogen evolution reaction (HER) of
Abstract Ring opening of extremely hydrophobic epoxides with water, amines, sodium azide and thiophenol was realized in the mixture solvent of water and 1, 4-dioxane under reflux condition. Hot water was believed to act as a mild Brønsted acid catalyst in the epoxide-opening reactions....
