Give the properties and uses of Sodium chloride.

1.	Give the properties and uses of Sodium chloride.
Answer» Properties and uses of sodium chloride: Common salt is a colourless and crystalline ionic compound. There is no water of crystallization in its crystalline structure. It is a neutral salt, salty in taste. This compound is used for the production of salts like Na₂CO₃ , NaHCO₃. When an electric current is passed through a saturated solution of sodium chloride (brine), it is electrolysed and hydrogen gas is released at the cathode while chlorine gas is released at the anode. This method is used for production of chlorine gas. In this method an important basic compound NaOH is formed in the cell. 2NaCl + 2H₂O → 2NaOH + Cl₂ ↑ + H₂ ↑ When salt is heated to a high temperature (about 800 °C), it melts. This is called the fused state of the salt. When fused salt is electrolysed, chlorine gas is released at the anode and liquid sodium metal, at the cathode.
