Question

(b) Explain the various properties of
water.
​

Answer 1

Answer:

Unique properties of water

Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is more electronegative, meaning that it is better than hydrogen at attracting electrons. Water is an excellent solvent.

Answer 2

Unique properties of water

Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is more electronegative, meaning that it is better than hydrogen at attracting electrons. Water is an excellent solvent

Water is a colourless, tasteless, and transparent liquid. It also has no smell.

⋅ Boiling point of pure water is 100∘C at 760 mm of Hg pressure. However, boiling point of water increases due to increase in pressure and presence of dissolved impurities.

⋅ Pure water freezes at 0∘C at 760 mm of Hg pressure. However, freezing point of water decreases due tpapĺàlàao increase in pressure and presence of dissolved impurities.

⋅ The state of water changes on heating or cooling. On heating, the state of water changes from liquid state to gaseous state (vapour). Similarly, on cooling, the state of water changes from liquid state to solid state (ice).

⋅ Water is neither acidic nor basic. It is neutral.

⋅ Water is a bad conductor of heat and electricity.

⋅ Water is an universal solvent as it can dissolve many substances in it.
