chlorinated water is water purified with chlorine (kills germs)

chloride MICl
where MI = metal

Se refiere al agua que contiene al clururo en forma de sal, principalmente de un metal alcalino.

CLORURADA: Agua que contiene sales procedentes del ácido clorhídrico. Es una combinación del cloro con un metal; el más conocido es el cloruro sódico o sal común.

Frase: "El agua clorurada tiene un sabor salado".

Chlorinated water does not refer to water containig chloride (Cl^) which is not of much use for killing germs. They msy add Cl_2 and/or other cholrine containing substances to eventually get , I think the hypochlorite ion (HClO^-) which is the active ingredient.

Thus, as we can see (below) Cl_2 gas is not what is added to water ... but a hypochlorite (ClO^-) which can geberate cholrine in small amounts....


Chlorine
The most commonly used disinfectant for swimming pools is chlorine. In its elemental form chlorine is a heavy greenish yellow gas which is so toxic that is has been used as a weapon in chemical warfare. Because of the extremely high potential for injury or death from improper use of chlorine gas, a number of chlorine compounds have been formulated to provide chlorine in forms that can be handled and used safely by swimming pool operators.

Thus, chlorinated water does not mean water to which Cl_2 gas has been added (too dangerous) but a hypochlorite which generates Cl_2 gas "in situ" (i.e. on site).

To SCI-DE and Elizabeth:

Thank you for your comments. The point is this. I know that there is chloridation and chlorination. However, in water chemistry, if the end results is Cl_2 (chlorine) it is called "chlorination" to the beast of my knowledge. Chloridation is more commonly used to refer to adding a chloride atom to a molecular site... I don't mind the use of chloridation, as long as we realise that Cl^- is not the active ingredient. At the end it is Cl_2 --- which is chlornie.
