However, these bonds are strong enough to create many of the peculiar properties of water, some of which make it integral to life. The molecules of water are constantly moving concerning each other, and the hydrogen bonds are continually breaking and reforming at timescales faster than 200 femtoseconds (2 × 10 −13 seconds).

This unique property of water is due to hydrogen bonding. Under standard conditions, water is primarily a liquid, unlike other analogous hydrides of the oxygen family, which are generally gaseous. Large ice crystals, as in glaciers, also appear blue. This can easily be observed in a water-filled bath or wash-basin whose lining is white. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color. Water is a tasteless, odorless liquid at ambient temperature and pressure. Water is the chemical substance with chemical formula HĢO one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Is a constant, so their respective concentrations are inversely proportional to each other. The product of the activities, or approximately, the concentrations of H + Related to its amphoteric character, it undergoes self-ionization. Water is amphoteric, meaning that it can exhibit properties of an acid or a base, depending on the pH of the solution that it is in it readily produces both H + Its hydrogen bonding causes its many unique properties, such as having a solid form less dense than its liquid form, a relatively high boiling point of 100 ☌ for its molar mass, and a high heat capacity. This polarity allows it to dissociate ions in salts and bond to other polar substances such as alcohols and acids, thus dissolving them. Water molecules form hydrogen bonds with each other and are strongly polar. It is also the third most abundant molecule in the universe (behind molecular hydrogen and carbon monoxide). It is the most abundant substance on the surface of Earth and the only common substance to exist as a solid, liquid, and gas on Earth's surface.

It is by far the most studied chemical compound and is described as the 'universal solvent' and the 'solvent of life'. Water ( H 2O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. Partially miscible with diethyl ether, methyl ethyl ketone, dichloromethane, ethyl acetate, bromine.ģ.1690 kilopascals or 0.031276 atm at 25 ☌ Miscible with methanol, ethanol, propanol, isopropanol, acetone, glycerol, 1,4-dioxane, tetrahydrofuran, sulfolane, acetaldehyde, dimethylformamide, dimethoxyethane, dimethyl sulfoxide, acetonitrile. Improved solubility in carboxylates, alcohols, ketones, amines. Poorly soluble in haloalkanes, aliphatic and aromatic hydrocarbons, ethers. On the other hand, the kinematic viscosity tells about the speed the fluid reaches when a particular force is applied to the fluid. When choosing between the two viscosities, it is worth noting that dynamic viscosity tells us about the force required to move the fluid at a certain speed. The larger the force or stress needed to move the plate, the more viscous the fluid is.
