H 2 Se adopts a bent structure with a H−Se−H bond angle of 91° [citation needed]. Consistent with this structure, three IR-active vibrational bands are observed: 2358, 2345, and 1034 cm −1. [6] The properties of H 2 S and H 2 Se are similar, although the selenide is more acidic with pK a = 3.89 and the second pK a = 11, [6] or 15.05 ± 0 ...

Sodium hydride is the chemical compound with the empirical formula Na H. This alkali metal hydride is primarily used as a strong yet combustible base in organic synthesis. NaH is a saline (salt-like) hydride, composed of Na + and H − ions, in contrast to molecular hydrides such as borane, silane, germane, ammonia, and methane.

Ammonium hexafluorosilicate. Fluorosilicic acid. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Sodium fluorosilicate is a compound with the chemical formula Na 2 [SiF 6 ]. Unlike other sodium salts, it has a low solubility in water.
Sodium–hydrogen antiporter. The sodium–hydrogen antiporter or sodium–proton exchanger ( Na+/H+ exchanger or NHX) is a membrane protein that transports Na + into the cell, and H + out of the cell ( antiport ). Na + /H + antiporter 1. Identifiers. Symbol.
Sodium hydroselenide is an inorganic compound with the chemical formula Na Se H. It is a salt of hydrogen selenide. It consist of sodium cations Na+ and hydroselenide anions −SeH. Each unit consists of one sodium, one selenium, and one hydrogen atom. Sodium hydroselenide is a selenium analog of sodium hydroxide NaOH.
