Question:
The increase in the solubility of Sodium halides, in water at 25°C is:
The increase in the solubility of Sodium halides, in water at 25°C is:
Show Hint
Larger ions like iodide (I-) tend to form weaker ionic bonds with sodium, making NaI more soluble in water than NaBr and NaCl.
Updated On: Mar 25, 2025
- NaCl > NaBr > NaI
- NaBr > NaI > NaCl
- NaI > NaBr > NaCl
- NaCl = NaBr > NaI
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The solubility of sodium halides in water increases in the order NaI>NaBr>NaCl. This is due to the ionic size and the lattice energy of the salts.
