Chemical properties of water:
1.) Since oxygen has a higher electronegativity than hydrogen, water is a polar molecule. The oxygen has a slight negative charge while the hydrogens have a slight positive charge giving the article a strong effective dipole moment. The interactions between the different dipoles of each molecule cause a net attraction force associated with water's high amount of surface tension.
2.) Water is a very strong solvent, referred to as the universal solvent, dissolving many types of substances. Substances that will mix well and dissolve in water, e.g. salts, sugars, acids, alkalis, and some gases: especially oxygen, carbon dioxide (carbonation), are known as "hydrophilic" (water-loving) substances, while those that do not mix well with water (e.g. fats and oils), are known as "hydrophobic" (water-fearing) substances.
3.) All the major components in cells (proteins, DNA and polysaccharides) are also dissolved in water.
4.) Pure water has a low electrical conductivity, but this increases significantly upon solvation of a small amount of ionic material such as sodium chloride.
5.) Pure water has a low electrical conductivity, but this increases significantly upon solvation of a small amount of ionic material such as sodium chloride.
6.)Water has the second highest specific heat capacity of any known chemical compound, after ammonia, as well as a high heat of vaporization (40.65 kJ mol−1), both of which are a result of the extensive hydrogen bonding between its molecules. These two unusual properties allow water to moderate Earth's climate by buffering large fluctuations in temperature.
7.) ADR label for transporting goods dangerously reactive with waterWater is miscible with many liquids, for example ethanol, in all proportions, forming a single homogeneous liquid. On the other hand, water and most oils are immiscible usually forming layers according to increasing density from the top. As a gas, water vapor is completely miscible with air.
8.) Water forms an azeotrope with many other solvents.
9.) Water can be split by electrolysis into hydrogen and oxygen.
10.) Elements which are more electropositive than hydrogen such as lithium, sodium, calcium, potassium and caesium displace hydrogen from water, forming hydroxides. Being a flammable gas, the hydrogen given off is dangerous and the reaction of water with the more electropositive of these elements is violently explosive.
11.) As an oxide of hydrogen, water is formed when hydrogen or hydrogen-containing compounds burn or react with oxygen or oxygen-containing compounds. Water is not a fuel, it is an end-product of the combustion of hydrogen. The energy required to split water into hydrogen and oxygen by electrolysis or any other means is greater than the energy released when the hydrogen and oxygen recombine.
Physical properties of water:
1.) Water is a tasteless, odorless liquid at ambient temperature and pressure. The color of water and ice is, intrinsically, a very light blue hue, although water appears colorless in small quantities. Ice also appears colorless, and water vapor is essentially invisible as a gas.
2.) Water is transparent, and thus aquatic plants can live within the water because sunlight can reach them. Only strong UV light is slightly absorbed.
3.) Another very important force that causes the water molecules to stick to one another is the hydrogen bond.
4.) The boiling point of water (and all other liquids) is directly related to the barometric pressure. For example, on the top of Mt. Everest water boils at about 68 °C (154 °F), compared to 100 °C (212 °F) at sea level. Conversely, water deep in the ocean near geothermal vents can reach temperatures of hundreds of degrees and remain liquid.
5.) Water sticks to itself. Water has a high surface tension caused by the strong cohesion between water molecules because it is polar. The apparent elasticity caused by surface tension drives the capillary waves.
6.) Water also has high adhesion properties because of its polar nature.
7.) Capillary action refers to the tendency of water to move up a narrow tube against the force of gravity. This property is relied upon by all vascular plants, such as trees.
8.)The maximum density of water is at 3.98 °C (39.16 °F).[6] Water becomes even less dense upon freezing, expanding 9%. This causes an unusual phenomenon: ice floats upon water, and so water organisms can live inside a partly frozen pond because the water on the bottom has a temperature of around 4 °C (39 °F).

it is hydrogen and electrons
Ware the main properties of parallels and meridians
Salinity causes the water to forget it's properties and relatives.

The physical properties of water can change when a compound is dissolved in water. The dissolved compound will determine which properties change. Some will change the surface tension, others will change the pH. Many changes are possible.

One of the main properties of water is its versatility: the water molecule is and acts like a dipole magnet. -
Acid and base when mixed in equal concentration neutralize each other.So if the water has both in equal concentration the water will not show the properties of the acid or the base.if any one i.e. acid or base is higher in concentration than the other the water will show its properties.
it is hydrogen and electrons

Is reacts with water not a chemical properties
The polarity of the water molecule is responsible for most of water's properties.
These physical properties depends on the water temperature.
A person who studies water and its properties is called a Hydrogeologist.

Salinity causes the water to forget it's properties and relatives.
hydrogen and oxygen makes up water but i think that is the most important properties of water
