Properties Of Solids

Part 1 Properties of deliquescent substance:
- Certain water-soluble substances, when exposed to the atmosphere at ordinary temperature.
- Absorb moisture from the atmospheric air to become moist.
- It ultimately dissolved in the absorbed water, forming a saturated solution.
- Such substance is called deliquescent substances.
Part 2 Find deliquescent substance from given option :
- Zinc chloride , is a colourless or white coloured chemical compound that is highly soluble in water.
- When it is exposed to the atmosphere at any temperature, absorb moisture from the atmospheric air to become moist.
- Ultimately dissolve in the absorbed water, forming a saturated solution.
Hence, Zinc chloride , is a deliquescent substance.
