Sodium bicarbonate ( IUPAC name: sodium hydrogencarbonate[ 9] ), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation ( Na +) and a bicarbonate anion ( HCO 3− ). Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder.
Bicarbonate. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). In inorganic chemistry, bicarbonate ( IUPAC -recommended nomenclature: hydrogencarbonate[ 2]) is an intermediate form in the deprotonation of carbonic acid. It is a polyatomic anion with the chemical formula H C O −.
The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.
Sodium carbonate decahydrate (Na 2 CO 3 ·10H 2 O), also known as washing soda, is the most common hydrate of sodium carbonate containing 10 molecules of water of crystallization. Soda ash is dissolved in water and crystallized to get washing soda. It is one of the few metal carbonates that is soluble in water.
Trinitrotoluene ( / ˌtraɪˌnaɪtroʊˈtɒljuiːn / ), [ 5][ 6] more commonly known as TNT (and more specifically 2,4,6-trinitrotoluene ), and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene[ 1], is a chemical compound with the formula C 6 H 2 (NO 2) 3 CH 3.
Sodium-ion batteries ( NIBs, SIBs, or Na-ion batteries) are several types of rechargeable batteries, which use sodium ions (Na +) as their charge carriers. In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, but it replaces lithium with sodium as the intercalating ion.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
In chemistry and thermodynamics, the standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements in their reference state, with all substances in their standard states. The standard pressure value p⦵ = 105 Pa (= 100 kPa = 1 ...
