Important Physical and Chemical Properties of Water

What is water?

Water is the concoction substance with synthetic equation H2O, one particle of water has two hydrogen iotas covalently attached to a solitary oxygen molecule. Give us a chance to find out about the physical and concoction properties of water.

Properties of Water

A look of earth taken from space will delineate it blue in shading. This blue shading is really water, the real piece of the earth is secured with water. We need water for nearly everything, for instance drinking, washing, cooking and so forth and thusly we should think about the properties of water. 65 % human body is made out of water. Water is fundamental for the survival of life on earth. Water is circulated unevenly on the world’s surface. It frames a noteworthy dissolvable and breaks down pretty much every polar solute. So given us a chance to view its properties and comprehend the explanation behind its criticalness:


Physical properties of water

Water is dreary and dull fluid. The particles of water have broad hydrogen bonds coming about to strange properties in the consolidated structure. This likewise prompts high dissolving and breaking points. When contrasted with different fluids, water has a higher explicit warmth, warm conductivity, surface strain, dipole minute and so on. These properties structure the purpose behind its criticalness in the biosphere. Water is a great dissolvable and accordingly it helps in the transportation of particles and atoms required for digestion. It has a high inactive warmth of vaporization which helps in the guideline of body temperature.

Water exists as a tasteless, odorless, and transparent liquid at room temperature. It is a chemical compound containing two hydrogen atoms and one oxygen atom (which are chemically bonded together via polar covalent bonds). The chemical formula of water is H2O. Being one of the most abundant compounds on the planet, this compound is often referred to as the ‘universal solvent’. Water molecules participate in intermolecular hydrogen bonding, making them highly polar. The critical temperature of H2O is 647 K. Other important physical and chemical properties of water are listed below.

The molar mass of water is 18.01 grams per mole. The melting point of this compound is 0oC and its boiling point corresponds to 99.98oC. Pure water is an insulator of electric current. However, due to the presence of dissolved ions (since it is a polar solvent), water with even small amounts of dissolved salts proves to be an excellent conductor of electricity.

Since water has a high dielectric constant, it proves to be a very good solvent. Under standard conditions, H2O molecules dissociate into hydroxide ions (OH) and hydronium ions (H3O+). As per the Bronsted-Lowry theory of acids and bases, an acid is an H+ ion donator whereas a base is an H+ ion acceptor. Water, therefore, is amphoteric in nature (it can act as an acid as well as a base).

For the compounds that exhibit isomerism, the isomers may display varying solubilities in water. For example, maleic acid has a solubility of 478.8 g/L in water but its trans isomer (fumaric acid) has a solubility of only 4.9 grams per liter in water.
