The carbonate ion is the simplest oxocarbon anion. It consists of one carbon atom surrounded by three oxygen atoms, in a trigonal planar arrangement, with D3h molecular symmetry. It has a molecular mass of 60.01 g/mol and carries a total formal charge of −2. It is the conjugate base of the hydrogencarbonate (bicarbonate) [8] ion, HCO− 3 ...
Sodium hypochlorite is an alkaline inorganic chemical compound with the formula Na O Cl (also written as NaClO). It is commonly known in a dilute aqueous solution as bleach or chlorine bleach. It is the sodium salt of hypochlorous acid, consisting of sodium cations (Na +) and hypochlorite anions (− OCl, also written as OCl − and ClO −
碳酸钠（英語： sodium carbonate ），俗稱苏打（soda）、纯碱 （soda ash 、soda crystals）、洗滌鹼（washing soda）。化学式：Na 2 CO 3 ，普通情况下为白色粉末，为强电解质。密度为2.532g/cm 3 ，熔点为850℃，易溶于水，並呈鹼性。具有鹽的通性。
"Ethyl carbonate"is the name commonly used in chemistry. Important non-medical esters with that group are Diethyl carbonate, (H 3 C–CH 2 –O–) 2 C=O; methyl ethyl carbonate, (H 3 C–OC(=O)O–C 2 H 5; Alkali salts of that anion, such as sodium ethyl carbonate, are known and fairly stable at ambient conditions
The chemical abbreviation for sodium was first published in 1814 by Jöns Jakob Berzelius in his system of atomic symbols, and is an abbreviation of the element's Neo-Latin name natrium, which refers to the Egyptian natron, a natural mineral salt mainly consisting of hydrated sodium carbonate. Natron historically had several important ...
Sodium metabisulfite or sodium pyrosulfite (IUPAC spelling; Br. E. sodium metabisulphite or sodium pyrosulphite) is an inorganic compound of chemical formula Na 2 S 2 O 5. The substance is sometimes referred to as disodium metabisulfite. It is used as a disinfectant, antioxidant, and preservative agent. [2]
In the laboratory, sodium formate can be prepared by neutralizing formic acid with sodium carbonate. It can also be obtained by reacting chloroform with an alcoholic solution of sodium hydroxide. CHCl 3 + 4 NaOH → HCOONa + 3 NaCl + 2 H 2 O. or by reacting sodium hydroxide with chloral hydrate. C 2 HCl 3 (OH) 2 + NaOH → CHCl 3 + HCOONa + H 2 O
