Sodium sulfite (sodium sulphite) is the inorganic compound with the chemical formula Na 2 SO 3.A white, water-soluble solid, it is used commercially as an antioxidant and preservative.
Solutions of bisulfite are typically prepared by treatment of sulfur dioxide with aqueous base: [3]. SO 2 + OH − → HSO − 3. HSO − 3 is the conjugate base of sulfurous acid, (H 2 SO 3).
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
Sulfurous acid is commonly known to not exist in its free state, and due to this, it is stated in textbooks that it cannot be isolated in the water-free form. [4] However, the molecule has been detected in the gas phase in 1988 by the dissociative ionization of diethyl sulfite. [5]
Al 2 Si 2 O 7, (Al 2 O 3 ·2SiO 2), called metakaolinite, formed from kaolin by heating at 450 °C (842 °F). [5] Al 6 Si 2 O 13, (3Al 2 O 3 ·2SiO 2), the mineral mullite, the only thermodynamically stable intermediate phase in the Al 2 O 3-SiO 2 system at atmospheric pressure. [6] This also called '3:2 mullite' to distinguish it from 2Al 2 O ...
Sodium bisulfate, also known as sodium hydrogen sulfate, [a] is the sodium salt of the bisulfate anion, with the molecular formula NaHSO 4.Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically in the form of either sodium hydroxide (lye) or sodium chloride (table salt).
