Water and its properties
Physical properties Pure water is an odorless and tasteless liquid. It has a bluish tint. The freezing point of water is 0 ̊ C at standard atmospheric pressure (1 atm) or 760 mm Hg or 760 torr. The boiling point of water is 100 ̊ C (212 ̊ F) at 1 atm. Water is at its maximum density at a temperature of 4 ̊ C (39 ̊ F).
Physical properties High specific heat: Water can absorb a large amount of heat energy before its temperature increases significantly. Solvent action: Water cab dissolve many substances. This is because of its polar nature, which allows it to interact with both positively and negatively charged ions. Surface tension
Structure of water is tetrahedral. The molecule is electrically neutral, but its O-H bonds are polar. The forces of attraction that exist in water is H-bond.
Chemical properties Water reacts with many metals, particularly alkali metals and alkaline earth metals. This reaction produces hydrogen gas and a metal hydroxide. 2 Na(s) + 2 H ₂O(l) 2 NaOH( aq ) + H₂(g)
Chemical properties Water reacts with metals. b. aluminum, zinc, and iron react with steam at high temperature, forming hydrogen and metallic oxides.
Chemical properties Water reacts with nonmetals: water reacts with some nonmetals, such as halogens to form acids. Cl ₂ (g) + H ₂O(l) HCl( aq ) + HClO ( aq ) Water reacts with metallic oxides. Soluble oxides like CaO and Na ₂O react with water to form hydroxide. Water reacts with nonmetallic oxides. CO₂, SO₂, and N₂O₅ react with water to form acids.
HYDRATES. Water can combine with some salts to form hydrates, which are solids that contain water molecules as part of their crystalline structure. The water in the hydrate is called water of crystallization or water of hydration.
USES OF WATER INDUSTRIAL USES 1. Water is part of the product. - manufacturing soft drinks, beer, pastry, and canned foods as well as in the formulation of drugs, lotions, cleaning agents, etc. 2. Water is used in the processing of the product. - Huge quantities of water are used in making paper, but the greater part of it does not stay with the product. - cleaning containers like bottles and cans where manufactures products are packed. 3. Water is used for cooling the product. - Water maybe piped through a steel mill to absorb heat from the furnace and molten metals.
USES OF WATER AGRICULTURAL USES 1. Irrigation of land 2. Artificial reservoirs DOMESTIC USES 1. Drinking 2. Bathing 3. Household cleaning 4. Watering plants 5. Laundry purposes
