When chlorine water is exposed to sunlight, it can undergo a reaction that produces hydrochloric acid and oxygen gas. This reaction is a form of photochemical decomposition, where the energy from sunlight breaks down the chlorine water into its constituent elements.

What happens to chlorine water on standing in the absence of sunlight?

Without sunlight, chlorine in water will slowly dissipate through evaporation, reacting with organic matter or forming chloramines. This process can take longer compared to when exposed to sunlight, as the degradation of chlorine is accelerated by UV radiation.


What gas is evolved when chlorine is passed into water and subsequently exposed to sunlight?

Oxygen gas is evolved when chlorine is passed into water and subsequently exposed to sunlight, which causes the chlorine to react with water, releasing oxygen and forming hypochlorous acid.


Does chlorine evaporate out of water?

Yes, chlorine can evaporate out of water over time, especially when the water is exposed to air or sunlight.


What products are formed when chlorine water is exposed to sunlight?

When chlorine water is exposed to sunlight, it can produce a mixture of chemicals including hypochlorous acid, hydrochloric acid, and oxygen. In the presence of organic matter, additional byproducts such as chloroform and other disinfection byproducts may also form.


Why chlorine water when exposed to direct sunlight forms a hydrochloric acid?

When chlorine water is exposed to direct sunlight, it undergoes a photochemical reaction that produces free radicals like chlorine atoms. These radicals react with water to form hydrochloric acid and hypochlorous acid. The hydrochloric acid is produced as a result of the chlorine radicals combining with water molecules.


What products are formed when chlorine is exposed to sunlight?

chlorine water + sunlight gives chlorine and oxygen in normal STP conditions .


How do you get rid of the chlorine odor from backwash?

Chlorine in water will dissipate if left exposed to the air and sunlight for a while e.g to get rid of chlorine in bucket of water leave it standing out in the sun for a while.


Does chlorine evaporate from water?

Yes, chlorine can evaporate from water. When water containing chlorine is exposed to air, the chlorine can escape into the atmosphere as a gas.


Does boiling pool water remove chlorine?

Boiling pool water will not remove chlorine completely. Chlorine is a volatile compound that can dissipate over time when exposed to air and sunlight. The most effective way to remove chlorine from pool water is through chemical treatment or filtration systems.

Can chlorine decay?

Yes, chlorine can decay through various chemical reactions and processes, such as reacting with other chemicals or breaking down due to exposure to sunlight. In water treatment, chlorine is added to disinfect water, but it can also decay over time, especially when exposed to organic matter.


What happens when an expose part of a mirror is under water and exposed to direct sun light?

The water acts as a magnifying glass, focusing sunlight on the mirror surface. This concentrated sunlight can create intense heat, potentially damaging the mirror or causing a fire hazard. It is important to ensure that mirrors are not exposed to direct sunlight when submerged in water to prevent any accidents.
