Kids learn about the element chlorine and its chemistry including atomic weight, atom, uses, sources, name, and discovery. Plus properties and characteristics of chlorine.
21 Νοε 2023 · The reaction of chlorine in water is a disproportionation reaction in which the chlorine gets both oxidised and reduced. Cl2 (aq) + H2O (l) → HCl (aq) + HClO (aq) The ionic equations show that the chlorine undergoes disproportionation, i.e. gets both oxidised and reduced.
When chlorine gas is dissolved in water, the reaction forms hypochlorous acid and hydrochloric acid: Cl 2 (chlorine gas) + H 2 O = HOCl (hypochlorous acid) + HCl (hydrochloric) When a hypochlorite is added to water, the reaction forms hypochlorite ion and hydroxide: NaOCl (sodium hypochlorite) + H 2 O = OCl¯ (hypochlorite ion) + OH (hydroxide)
Generate chlorine gas on a microscale and investigate its reactions with water or halide ions in this class practical. Includes kit list and safety instructions.
Water from rivers, lakes and the sea has to be treated to make it safe to use and drink. Different methods are used to do this, such as sedimentation, filtration and chlorination.
Chlorine kills bacteria and viruses through a simple chemical reaction. The chlorine solution breaks down into different chemicals, including hypochlorous acid (HOCl) and hypoclorite ion (OCl-). Both of these chemicals kill microorganisms by destroying the enzymes and structures inside the cell.
When chlorine enters water, it immediately begins to react with compounds found in the water. The chlorine will react with organic compounds and form trihalomethanes. It will also react with reducing agents such as hydrogen sulfide, ferrous ions, manganous ions, and nitrite ions.
