The Homestake experiment (sometimes referred to as the Davis experiment or Solar Neutrino Experiment and in original literature called Brookhaven Solar Neutrino Experiment or Brookhaven 37 Cl (Chlorine) Experiment) [1] was an experiment headed by astrophysicists Raymond Davis, Jr. and John N. Bahcall in the late 1960s.
Acetyl hypochlorite is reported to be produced by the reaction of acetic anhydride and dichlorine monoxide at very low temperatures: [2]. Cl 2 O + (CH3CO) 2 O → 2CH 3 COOCl. The liquid can be distilled at reduced pressure, however it cannot be heated, as it violently decomposes at 100 °C to acetic anhydride, oxygen, and chlorine gas, and reacts with water and alcohols.
The grade of chlorine-based bleaches is often expressed as percent active chlorine. One gram of 100% active chlorine bleach has the same bleaching power as one gram of elemental chlorine. The most common chlorine-based bleaches are: Sodium hypochlorite (NaClO), usually as a 3–6% solution in water, usually called "liquid bleach" or just "bleach".
The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus. [citation needed] Chlorine adds to the multiple bonds on alkenes and alkynes as well, giving di- or tetra-chloro compounds. [citation needed]
Chlorine trifluoride is an interhalogen compound with the formula ClF 3. It is a colorless, poisonous, corrosive, and extremely reactive gas that condenses to a pale-greenish yellow liquid, the form in which it is most often sold (pressurized at room temperature).
It has the same molecular shape as chlorine trifluoride. Iodine trifluoride (IF 3) is a yellow solid that decomposes above −28 °C. It can be synthesised from the elements, but care must be taken to avoid the formation of IF 5. F 2 attacks I 2 to yield IF 3 at −45 °C in CCl 3 F. Alternatively, at low temperatures, the fluorination reaction

A dechlorinator is a chemical additive that removes chlorine or chloramine from water. Where tap water is chlorinated, it should be dechlorinated before use in an aquarium, since chlorine can harm aquatic life in the same way it kills micro-organisms. Chlorine will kill fish [20] and cause damage to an aquarium's biological filter. [21]
