State the Properties of Sodium chloride.

1.	State the Properties of Sodium chloride.
Answer» Properties of Sodium chloride • Sodium chloride is a white crystalline solid having a density of 2.17 g/ml. • It melts at 1080 K (807°C) and boils at 1713 K (1440°C). • It is soluble in water and its solubility is 36 g per 100 g of water at 273 K. (0°C). The solubility in water remains constant with temperature. • Pure sodium chloride is non-hygroscopic, but behaves as hygroscopic due to the impurities of CaCl₂ and MgCl₂ in it. • Solid Sodium chloride does not conduct electricity at room temperature but molten sodium chloride is a very good ionic conductor.

Properties of Sodium chloride

• Sodium chloride is a white crystalline solid having a density of 2.17 g/ml.

• It melts at 1080 K (807°C) and boils at 1713 K (1440°C).

• It is soluble in water and its solubility is 36 g per 100 g of water at 273 K. (0°C). The solubility in water remains constant with temperature.

• Pure sodium chloride is non-hygroscopic, but behaves as hygroscopic due to the impurities of CaCl₂ and MgCl₂ in it.

• Solid Sodium chloride does not conduct electricity at room temperature but molten sodium chloride is a very good ionic conductor.
