How Long to Boil Water to Remove Chlorine


It is necessary to boil water for one minute to remove chlorine. This is true whether you are using a stovetop or microwave method. Be sure to let the water cool before drinking it, as boiling water can scald you.

Does boiling tap water remove chlorine?

If you are using municipal tap water to fill your aquarium, it is likely that the water contains chlorine. While chlorine is not harmful to fish in low concentrations, it can be detrimental to their health if the concentration is too high. Boiling the water for a few minutes will remove most of the chlorine from the water and make it safe for your fish.

Let Water Sit to Remove Chlorine

If you’re like most people, you probably think that the water coming out of your tap is clean and safe to drink. Unfortunately, that’s not always the case. Chlorine is a chemical that’s often used to disinfect water, but it can also be harmful to your health.

Drinking water with chlorine in it has been linked to an increased risk of cancer, and it can also cause skin irritation and respiratory problems. The good news is that there are ways to remove chlorine from your water. One of the easiest ways is to simply let your water sit for 24 hours before you drink it.

This gives the chlorine time to evaporate, leaving you with safe, clean water to drink.

Can Boiled Water Remove Chlorine?

When it comes to removing chlorine from water, boiling is an effective method. Chlorine is a gas at room temperature, so when water is boiled, the chlorine evaporates and leaves behind clean water. This process can be repeated multiple times to further remove any traces of chlorine.

While boiling is an effective way to remove chlorine from water, it’s not the only method. There are also filters that can be used to remove chlorine (and other impurities) from water. These filters come in a variety of sizes and styles, so there’s sure to be one that meets your needs.

How Long Does It Take to Remove Chlorine from Water?

It takes around 4-6 hours to remove chlorine from water using a reverse osmosis filtration system. However, carbon filters can do it much faster, in as little as 30 minutes.

At What Temperature Does Chlorine Boil Out of Water?

Chlorine is a chemical element with the symbol Cl and atomic number 17. A halogen, it is a pale yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidizing agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only fluorine and oxygen.

The most common compound of chlorine, sodium chloride (common salt), has been known since ancient times. Around 1630, chlorine was recognized as a gas by the chemist Johann Joachim Becher. Its bleach properties were first observed by Carl Wilhelm Scheele in 1774, but he did not realize that it was an element.

In 1809, Claude Berthollet recognized bleaching powder (calcium hypochlorite) as containing chlorine; he attempted unsuccessfully to isolate it. French chemist Antoine Jerome Balard distilled elemental chlorine from a mixture of hydrochloric acid and sea salt in 1834 using iron as a catalyst, obtaining chloromethane (now methylene chloride). Balard’s student Edward Frankland named the element “chlorine”, from Greek χλωρός (khlōros), meaning greenish-yellow; Frankland used this name because some chlorinated compounds are colored yellow or green.[9]

The name “halogen” comes from Ancient Greek ἅλς háls “salt”[10] + -genes “born”. In water treatment plants for municipal drinking water supplies chlorination is employed to disinfect water before use;[41][42] bacteria present in raw water can often cause disease such as cholera if left untreated.[43][44] When added to drinking water small amounts of sodium hypochlorite or calcium hypochlorite dissolve releasing free chlorine atoms which react with water forming hydroxyl radicals (-OH).

These radicals are highly reactive attacking bacterial cell walls causing cell lysis (bursting).[45][46] Boiling does not drive off all of the residual chlorine in treated water; therefore many municipalities advise their residents to let tapwater stand for 24 hours prior to consumption if they do not wish to taste its flavor.[47][48]

At sufficiently high temperatures – above 100 °C – complete dechlorination occurs according to equation 4:[49]

How Do You Remove Chlorine from Tap Water?

If you’re concerned about the chlorine in your tap water, there are a few ways to remove it. One way is to let the water sit for 24 hours before using it. This will allow the chlorine to evaporate on its own.

Another way to remove chlorine from tap water is by boiling it. Boiling the water will cause the chlorine to evaporate quickly. Just be sure to let the water cool down before drinking it or using it for cooking.

You can also buy a water filter that is specifically designed to remove chlorine from your tap water. These filters are usually very affordable and easy to install. There are even some pitchers that have built-in filters that will remove chlorine from your water as you pour it into the pitcher.

Whatever method you choose, make sure you’re getting rid of as much of the chlorine as possible so that you can enjoy fresh, clean-tasting tap water every time!


It is recommended that you boil water for at least one minute to remove chlorine. This will ensure that the water is safe to drink and free of any harmful chemicals.
