What is the reaction between chlorine and water?
Chlorine will react in water to form hypochlorous acid, which can then dissociate into hydrogen and hypochlorite ions, according to Eqn (1). This reaction is very important, as the disinfecting power of HOCl, hypochlorous acid, is about 40–80 times that of OCl−, hypochlorite.

What is the chemical formula of chlorine?
Cl2
The chemical formula of chlorine gas is Cl2. It is yellow-green in colour and has an odour which is similar to to the household bleach. It is soluble in water and reacts to form hypochlorous acid and hydrochloric acid.
What is the correct equation for chlorination reaction?
The following equation presents the hydrolysis reaction (USEPA 1999; White 1992): Cl 2(g) + H 2 O ⇒ HO Cl + H + Cl − (2) The addition of chlorine gas to water reduces the pH of the water due to the production of hydrogen ion.
What is the formula for a chlorine molecule?
Formula and structure: the chemical structure of chlorine gas is Cl2 and its molecular weight is 70 g/mol. Its structure is Cl-Cl, which is also called the element form of the chlorine element, consist in 2 atoms of chlorine joined by a covalent bond.
Is the chlorine in tap water?
Quick Facts. Chlorine is added into our tap water supplies to help reduce the chance of harmful waterborne bacteria spreading through through the water, such as e. coli and the norovirus. The strength of this chlorine scent will usually depend on the distance of which your public water source is from your building.
Why is the formula for chlorine Cl2?
Chlorine is called Cl2 because it is a diatomic molecule. Diatomic means there are two atoms of the same elements in the molecule. There are other diatomic molecule, such as hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2).
Why is chlorine added to water?
Chlorination is the process of adding chlorine to drinking water to kill parasites, bacteria, and viruses. Using or drinking water with small amounts of chlorine does not cause harmful health effects and provides protection against waterborne disease outbreaks.
What is chlorination reaction?
Chlorination: Any reaction or process in which chlorine (and no other elements) are introduced into a molecule. Chlorination of an alkene by electrophilic addition of Cl2. Chlorination of a benzene ring by electrophilic aromatic substitution.
What is the formula of water?
H₂O
Water/Formula
H2O is the chemical formula of water. It means that each molecule of water is made up of two hydrogen atoms, indicated by the letter H, and a single oxygen atom, represented by the letter O.
