No, it contains H2O molecules along with OH- and H3O+ions from self-ionization. This is why water can still conduct some electricity.

Is the concentration of water molecules higher in pure water or in sugar water?
Concentration of water molecules is higher in pure water
How do you decrease the number of molecules in a glass of water without changing the number of water molecules?
If the water is impure, you could remove the impurities. If the water is pure, it's impossible to decrease the number of molecules without changing the number of water molecules, which would be the only kind of molecules present in that case.
Why does water contains two types of atoms if its a pure substance?
It sounds like you are confusing meaning of "substance" with the meaning of "element". A pure element is a single type of atom. A pure compound will contain only one type of molecules. The molecules may be made up of more than one element, but every molecule of the compound will have exactly the same elements in exactly the same ratios and bound in exactly the same structure. All water molecules are the same:: H2O. If the only type of molecule you have is H2O, you have "pure water"."Substance" just means "a particular kind of matter with uniform properties". Pure water will have uniform properties - note that those uniform properties are quite different from those that are displayed by elements that make it up when in their pure form; at room conditions water is liquid but pure hydrogen and pure oxygen are gases.Water is a pure substance but it is a compound and is made of oxygen and hydrogen.
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.
How many substances are present in a water and salt mixture?
depends on what salt it is and the purity of the water. if the water is 100% pure , then it contains only hydrogen and oxygen as molecules and if it is common salt then it contains sodium and chlorine as molecules
Is there a difference between carbonated water and pure water?
"Pure" water should contain only H2O, however, Carbonated water has carbon dioxide molecules forced into the mix.
Does carbon dioxide contain water?
No - they are separate molecules. Pure CO2 does not contain H2O.
Is it Salute is a part of Pure Water?
No. Pure water contains only water molecules.
Is the concentration of water molecules higher in pure water or in sugar water?
Concentration of water molecules is higher in pure water
What makes something a pure substance?
The fact that it can no longer be broken down. An element is pure because of how it cannot be broken further down.
What molecules are pure elements?
If a molecule is made of only one type of atom, then it is a pure element in molecular form. For example, hydrogen gas, as it was used in balloons before the Hindenburg caught fire, is a pure element. That gas consists of hydrogen molecules - H2. Hydrogen gas nearly always forms two-atom molecules and is still a pure element. The Oxygen in the air is a pure element but it also is only found as two-atom gas-molecules - O2. The well-known Buckyballs which are large molecules of carbon are nothing but carbon and therefore are molecules of one element - pure carbon.

What is flowing slower pure water or Perrier water?
Pure because it has less carbon molecules in it

Is pure water composed by molecules?
Yes, water is a molecule.
