What is the chemical composition of H2O?

What is the chemical composition of H2O?

Water (chemical formula: H2O) is a transparent fluid which forms the world’s streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds.

How do these properties make water unique?

Unique properties of water

  1. Water is polar.
  2. Water is an excellent solvent.
  3. Water has high heat capacity.
  4. Water has high heat of vaporization.
  5. Water has cohesive and adhesive properties.
  6. Water is less dense as a solid than as a liquid.

What allows ice to float?

Like most things that float, ice floats because it is less dense than liquid water. Ice is about 9% less dense. When ice forms, it takes up about 9% more space than it did as a liquid. Thus, a 1 liter container of ice weighs less than a 1 liter container of liquid water, and the lighter material floats to the top.

What Colour is water?

The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.

What is a property of pure water?

Physical Properties of Pure Water: 1. Pure water is a colorless, tasteless and odorless liquid. Distilled water is pure. Drinking water has a pleasant taste because dissolved minerals and air in water make its taste better.

What are the 3 properties of water?

1 Answer. The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends.

What species are present in pure water?

we deduce that – pure water contains three chemical species, namely H_2O water, hydroxide ion OH^- and the hydronium ion (hydroxonium, oxonium) H_3O^+ – hydroxide and hydronium must be equal in concentration, because each time it appears or disappears an hydroxide ion, it appears or disappears an hydronium ion.
