Water does not contain other trace elements.
Tap water and purified water, on the other hand, contain substances other than water and are not pure.
Definition. It is defined as follows:
1. Pure substance refers to a polymer composed of a single substance or a compound, which is fixed in composition and has fixed physical properties.
and chemical properties of substances, which have special chemical symbols and can be represented by a chemical formula.
2. Tap water refers to the water produced by the tap water treatment plant that meets the corresponding standards for people's life and production.
3. Purified water refers to Ho without impurities, referred to as clean water or pure water, which is pure, clean, and does not contain impurities or bacteria, such as organic pollutants and inorganic salts.
Any additives and all kinds of impurities are in line with the sanitary standards of drinking water.
of water is raw water.
Characteristics of pure substances.
1. Substances with fixed composition and fixed physical and chemical properties.
2. There are special chemical symbols.
Examples: oxygen, nitrogen, potassium chlorate.
and so on, all of which are pure.
Conception. Macro: A polymer made up of one component.
Microscopic: Composed of particles of the same kind.
In the real universe, pure matter is only a theoretical state.

Tap water, purified water contains other impurities.
Water is pure, water consists of only one substance, a substance with fixed physical and chemical properties, and a special chemical symbol.
Tap water, purified water, in addition to water, also contains an impurity element such as salts. So, tap water, pure water is not pure.

1. There are broad concepts and narrow concepts, the broad concept is the various types of water we see, and the narrow concept is H2O.
The question should be a narrow concept.
2. Tap water is a mixture (solution) with water (H2O) as the main body, and purified water is a mixture (solution) with water as the main body and relatively few impurities.
3. Obviously, only water (H2O) is pure.
-
Tap water contains a lot of impurities, and the water is pure after filtration.
-
This is a chemistry problem, because tap water and pure water contain impurities.
-
What is the difference between purified water and tap water.
-
It's a mixture. Tap water refers to the water produced by the tap water treatment plant that meets the corresponding standards for people's life and production. Tap water goes through a number of complex processes.
Drinking water produced by specialized equipment.
Is tap water pure?
Tap water contains potassium, calcium, sodium, magnesium, and sulfate, which are indispensable to the human body.
Macroelements such as bicarbonate and chloride.
Domestic water is mainly absorbed from rivers, lakes and groundwater and surface water through the water intake pumping station of the water plant, which is processed by the waterworks in accordance with the "National Health Standards for Drinking Water Related to Shengshu Tonghu", and finally transported to various users through the water distribution pumping station.
Water is one of the most common substances on Earth. 71% of the Earth's surface is covered by water. It is an important resource for the survival of all life and the most important component of living organisms.

Pure water is tap water. refined. 0 cost. So sell cheaply. As long as the cost of transportation. 5 cents a bottle.
Difference Between Purified Water and Distilled Water.
Purified water is a clean aerobic molecule that contains trace amounts of mineral plants needed by the human body, and is also living water (fish do not die in it). Whereas distilled water is stagnant water (without oxygen the fish will die immediately in it). Purified water is not the same thing as distilled water at all, so distilled water cannot be compared to purified water. >>>More
I think there are two main reasons:
1.That is, purified water can be produced in large quantities, and the production process is relatively simple. The natural mineral water source is less selective, and the output will not be very large, and the real mineral water ** is relatively small. >>>More
Look at the concept of water purifier, if some minerals are retained, it is fine, because a large part of the minerals in the human body are ingested through water, and the intake from food alone cannot be satisfied. If the mineral content in the water is low or even none, then you should usually supplement with mineral tablets. >>>More
Boiled water or purified water Because they are soft water, there is no harm to the human body And pure water is hard water, which can be harmful if you drink it for a long time In recent years, with the change of people's consumption concepts and the enhancement of environmental awareness, mineral water, mineralized water, pure water, distilled water and space water have appeared on the market. Manufacturers of mineral water and mineralized water advertise that their drinks contain a variety of minerals needed by the human body, which can dispel diseases and strengthen the body, and are the best drinks; Some also claim that "mineral water is better than pure water, distilled water and space water, and these pure waters not only remove the harmful components of the human body, but also discard the beneficial components of the human body". Not to be outdone, the manufacturers of space water and pure water say that pure water has high purity, which is easy to dissolve food nutrients in water and be absorbed by the human body, and is easy to discharge harmful substances in the human body; Some even claim that "the human body does not need to absorb minerals from water, mineral water is harmful to the human body, and the biggest danger is the formation of stones". >>>More
Hot Springs 7 6 is a type of spring water, which is a type of spring water that naturally gushes from the ground, and its water temperature is 5 degrees Celsius or more than 10 degrees Fahrenheit per year. It is a hot spring water that is warm enough to take a bath, boil dumplings, blanch cabbage, and shabu mutton. Of course, because hot springs are naturally generated, water heated by a firewood fire or water heater is not considered a hot spring, but hot water at best. >>>More
