No water is entirely pure. Most water has minor impurities like dissolved salts of sodium and calcium; tap water in most countries has additional chlorides and fluorides to help kill off bacteria in the water. Some countries deliberately add forms of medication, e.g. in the UK, flouride is added to help contain dental caries (tooth decay). This is in addition to any chemicals needed to make water drinkable. My original answer, which was substantially correct, was removed - why? I am told by Wikianswers that it is polite to add to answers or comment on them, not delete them.

∙ 14y agoIn general it should be pure but it is in real not as in almost all part of world tap water is mixed with some chemicals to let it free from microbes and also to precipitate certain impurities
the compound mix generally are chlorine and hypochloride etc

∙ 13y agoNo, tap water contains many impurities including metals, minerals and dissolved gases. These generally come from the water source, the Plumbing materials and the atmosphere.
There are also a small amount of added impurities such as fluorides to keep the water sanitary and improve dental care, etc.
The concentrations of minerals in a water supply often defines it's taste. High mineral concentrations (Mg2+ and Ca2+ containing minerals, especially) lead to termed "hard water" areas, which has several connotations but are never the less not generally a health concern.
If you want to use water as a reagent in a lab, we use 'deionised' water, which has had many of the ionic (and thus water-soluble) impurities removed. Water can be further purified by 'degassing' which does exactly what the name suggests. It also makes the water taste absolutely foul.
I'll take slightly impure tap water any day.

∙ 12y agoYes, it is, from a medical standpoint of "potable" (safe for drinking) it is pure water, that is, it is guaranteed that there is nothing in it that can make you sick. It is not as pure as say, distilled water, but distilled water is flat and tasteless.

∙ 12y agoTap water contains traces of salts such as magnesium, calcium, carbonates, bicarbonates and others. Pure water does not.
Depending on the municipality where your tap water is delivered, there may be added chemicals included. As well, the groundwater source may contain minerals specific to the geography.
Pure water contains no minerals or added chemicals: it is pure H2O.

∙ 8y agoPure water without any level of dissolved solids or gases is almost impossible to find. Tap water is water treated to assure users that any materials in it are below levels which can cause harm to the users.
Wiki User
∙ 9y agoTap water has additives placed into it by municipalities to make it safer. Because of the added minerals, it is not pure water.

is tap water in a glass pure substances or mixture?
Tap water is not a pure substance. Water has particles in it. Some tap water also contains fluoride. Distilled water has all of the particles taken out of it and is considered pure water.
What type of mixture is tap water?
Unfiltered tap water is a pure substance
Is tap water an element compound heterogeneous mixture or homogeneous mixture?
Pure water (H2O) is a chemical compound; if the water is impure may be a homogeneous or heterogeneous mixture.
Is tap water and bottle water pure water to be neutral on the pH scale?
On the pH scale, tap water is very close to neutral. Tap water does contain impurities, and therefore is not pure water, so it is not completely neutral, but is very close to it.

Is tap water a pure substance a homogeneous substance or a heterogeneous substance?
Normal tap water can be considered as fairly pure and homogeneous; only ultrapure water is correctly pure. Sometimes tap water may contain insoluble impurities.
Is tap a pure substance?
Tap water is a mixture of water (H2O) and minerals used to purify it.
Is there a mass difference between pure water and tap water?
No. Water is water.
Is tap water colored blue a homogeneous mixture?
Pure tap water is water having only some infinitesimal impurities. Have you a blue tap water in your bath ?
What type of mixture is tap water?
Unfiltered tap water is a pure substance
Is tap water an element compound heterogeneous mixture or homogeneous mixture?
Pure water (H2O) is a chemical compound; if the water is impure may be a homogeneous or heterogeneous mixture.
Is your tap water pure water?
No, it has chlorine in it, and sometimes fluoride, as well.
What are the two types of water?
pure and impure water. That is correct but pure water is distilled water and impure water is tap water, or natural water.
