Chemistry · Colligative properties of dilute solutions: a relative lowering of vapour pressure, depression of freezing point, the elevation of boiling point and osmotic pressure
Solubility of in compared with its solubility in is:
Solubility of \( N a C l \) in \( D_{2} O, \) compared with its solubility in \( H_{2} O \) is:
- A. less
- B. equal
- C. more
- D. cannot be predicted
Step-by-step solution
D2O exhibits stronger hydrogen bonding than H2O due to the isotope effect, making it a less effective solvent for ionic compounds like NaCl. The stronger intermolecular forces in D2O require more energy to disrupt for solvation, reducing NaCl solubility.
