The primary decay mode of isotopes lighter than 35 Cl is electron capture to isotopes of sulfur; that of isotopes heavier than 37 Cl is beta decay to isotopes of argon; and 36 Cl may decay by either mode to stable 36 S or 36 Ar. [42] 36 Cl occurs in trace quantities in nature as a cosmogenic nuclide in a ratio of about (7–10) × 10 −13 to 1 ...

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.
Chlorine can be further oxidized to other oxides and oxyanions including hypochlorite (ClO −, the active ingredient in chlorine bleach), chlorine dioxide (ClO 2), chlorate (ClO − 3), and perchlorate (ClO − 4). In terms of its acid–base properties, chloride is a weak base as indicated by the negative value of the pK a of hydrochloric
Heat required to initiate this reaction is generated by oxidation of a small amount of iron powder mixed with the sodium chlorate, and the reaction consumes less oxygen than is produced. Barium peroxide (Ba O 2) is used to absorb the chlorine that is a minor product in the decomposition. [10] An ignitor charge is activated by pulling on the ...
Hydrochloric acid fumes turning pH paper red showing that the fumes are acidic. Hydrogen chloride is a diatomic molecule, consisting of a hydrogen atom H and a chlorine atom Cl connected by a polar covalent bond. The chlorine atom is much more electronegative than the hydrogen atom, which makes this bond
Chlorous acid is an inorganic compound with the formula HClO 2. It is a weak acid. Chlorine has oxidation state +3 in this acid. The pure substance is unstable, disproportionating to hypochlorous acid (Cl oxidation state +1) and chloric acid (Cl oxidation state +5): 2 HClO 2 → HClO + HClO 3
For example, comparing the potentials for zinc (-0.75 V) with those of iron (Fe(II) -0.47 V, Fe(III) -0.06 V) it is seen that iron ions are more easily reduced than zinc ions. This is the basis for using zinc to provide anodic protection for large structures made of iron or to protect small structures by galvanization.
