Read the following statementsi) Crystals of NaOH are deliquescentii) The by product formed in Solvay process is CaCl2iii) NaHCO3 is a mild antiseptic for skin infection

The substance which easily absorbs the moisture from the atmosphere are said to be deliquescent substances.High degree of hygroscopic nature of a substance is said to deliguescentSolvay process:NH3 + CO2 + H2O → NH4HCO3NH4HCO3 + NaCl → NH4Cl + NaHCO3 The ammonia is regenerated by treating the by-product NH4Cl with slaked lime [Ca(OH)2]2NH4Cl + Ca(OH)2 → 2NH3 + CaCl2 + 2H2O→ NaHCO3 is used as a mild antiseptic agent for skin infection.
