Why does common salt dissolve appreciably in water?
Answer and explanation
Correct answer: Because water is a polar solvent
Common salt, mainly sodium chloride, is an ionic compound, while water is a polar solvent. The partially negative oxygen end of water attracts sodium ions, and the partially positive hydrogen ends attract chloride ions. These ion–dipole attractions hydrate and separate the ions from the crystal, allowing them to spread through the solution. Salt does not dissolve because it is light or gaseous; its solubility results from these molecular interactions.
