Distilled water contains only H2O molecules since it is free from impurities. It is therefore, a compound. Since some impurities such as dust particles etc. are normally mixed with tap water, it is, therefore, a mixture.
How is distilled water a compound?
Distilled water is pure liquid H2O, which makes it a compound. … It is also not an element because water molecules are made of both hydrogen and oxygen. Distilled water, as long as it’s not contaminated with any other elements or compounds, is a compound.
Why is distilled water a compound while tap water is a mixture?
Distilled water is a compound because it contains only molecules of water . But in tap water it is a mixture because it contains minerals and vitamins in it.
Is distilled H2O a compound?
Water, H2O, is a pure substance, a compound made of hydrogen and oxygen. Although water is the most abundant substance on earth, it is rarely found naturally in its pure form. Most of the time, pure water has to be created. Pure water is called distilled water or deionized water.
Why is water called a compound Give two reasons?
Water is a molecule because it contains molecular bonds. Water is also a compound because it is made from more than one kind of element (oxygen and hydrogen). … This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type.
Is spring water pure chemistry?
However, spring water often contains many of the same impurities found in well or tap water. … The “pure” part actually refers to the source, not the water itself—in that 100% of that bottle’s contents came from an underground source (rather than surface water).
Is laundry detergent a mixture?
Water itself is an example of a homogeneous mixture. All but the purest water contains dissolved minerals and gases. … Liquid laundry detergent is another example of a homogeneous mixture of various soaps and chemicals for washing clothes.
Does chemically pure water exist?
Here’s the thing, though: Pure water doesn’t exist. … May Nyman, a chemistry professor at Oregon State University, told Live Science that water sucks up ions too readily from the surrounding environment to allow for truly pure water.
Is distilled water mixture?

Why is it bad to drink distilled water?
Distilled water is safe to drink. But you’ll probably find it flat or bland. That’s because it’s stripped of important minerals like calcium, sodium, and magnesium that give tap water its familiar flavor. What’s left is just hydrogen and oxygen and nothing else.
What can I use instead of distilled water?
4 Substitutes for Distilled Water

What is the purpose of distilled water?
Water that is purified through distillation will not leave behind any minerals, toxins or contaminants that would likely cause hard mineral buildup or clog a machine. Along the same lines, distilled water is recommended for drinking and cooking because it will not introduce any harmful substances into your body.
Who proved that water is a compound?
It was the chemist Henry Cavendish (1731 – 1810), who discovered the composition of water, when he experimented with hydrogen and oxygen and mixed these elements together to create an explosion (oxyhydrogen effect).
What is H2O a compound or element?
Вода/Название ИЮПАКFor example, water (H2O) is a compound consisting of two hydrogen atoms bonded to an oxygen atom. The atoms within a compound can be held together by a variety of interactions, ranging from covalent bonds to electrostatic forces in ionic bonds.

Who proved that water is a compound and not an element?
Water is not an element: Lavoisier. Of the four elements of the ancients, water is the only one which is a pure chemical substance, albeit a compound and not an element. It should not be surprising, then, that it was the last of the four to be shown not to be elementary.
