MCQ
The energy that opposes dissolution of a solvent is
  • A
    Hydration energy
  • B
    Lattice energy
  • C
    Internal energy
  • ✓
    Bond energy
✓

Answer

Correct option: D.
Bond energy
d
Lattice energy opposes the dissolution of a solvent. Lattice energy is the amount of energy required to dissociate $1\, mole$ of ionic crystal into ions.If the hydrated energy of solid is more than lattice energy, then slid dissolves.
