2 Cl 2 + 2 NaHCO 3 → Cl 2 O + 2 CO 2 + 2 NaCl + H 2 O. This reaction can be performed in the absence of water but requires heating to 150–250 °C; as dichlorine monoxide is unstable at these temperatures [4] it must therefore be continuously removed to prevent thermal decomposition. 2 Cl 2 + Na 2 CO 3 → Cl 2 O + CO 2 + 2 NaCl
Chlorine dioxide is a chemical compound with the formula ClO 2 that exists as yellowish-green gas above 11 °C, a reddish-brown liquid between 11 °C and −59 °C, and as bright orange crystals below −59 °C.
4 CoCl 2 + 8 en + 4 HCl + O 2 → 4 trans-[CoCl 2 (en) 2]Cl + 2 H 2 O The initial product contains HCl, which is removed by heating. Alternatively, (carbonato)bis(ethylenediamine)cobalt(III) chloride reacts with hydrochloric acid at 10 °C to give the same species.
Hypochlorous acid is an inorganic compound with the chemical formula Cl O H, also written as HClO, HOCl, or ClHO. [2] [3] Its structure is H−O−Cl.It is an acid that forms when chlorine dissolves in water, and itself partially dissociates, forming a hypochlorite anion, ClO −.
The tetrahydrate consists of octahedral cis-Mn(H 2 O) 4 Cl 2 molecules. The trans isomer, which is metastable, is also known. [4] [5] The dihydrate MnCl 2 (H 2 O) 2 is a coordination polymer. Each Mn center is coordinated to four doubly bridging chloride ligands. The octahedron is completed by a pair of mutually trans aquo ligands. [6]
Cobalt(II) chloride is an inorganic compound, a salt of cobalt and chlorine, with the formula CoCl 2.The compound forms several hydrates CoCl 2 ·n H 2 O, for n = 1, 2, 6, and 9. . Claims of the formation of tri- and tetrahydrates have not been confirmed
Chromium(II) chloride describes inorganic compounds with the formula Cr Cl 2 (H 2 O) n.The anhydrous solid is white when pure, however commercial samples are often grey or green; it is hygroscopic and readily dissolves in water to give bright blue air-sensitive solutions of the tetrahydrate Cr(H 2 O) 4 Cl 2.
Dichlorine monoxide (Cl 2 O) is a brownish-yellow gas (red-brown when solid or liquid) which may be obtained by reacting chlorine gas with yellow mercury(II) oxide. It is very soluble in water, in which it is in equilibrium with hypochlorous acid (HOCl), of which it is the anhydride.
