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
- Water is polar.
- Water is an excellent solvent.
- Water has high heat capacity.
- Water has high heat of vaporization.
- Water has cohesive and adhesive properties.
- 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.
