Questions
Statement 1: ionises in solution.
Statement 2: The hydration energy of exceeds the ionization energy.
detailed solution
Correct option is A
Ionization energy required to convert Al to Al3+ is 5137 kJ mol−1. ΔHhydration for Al3+ is −4665 kJ mol−1 and ΔHhydration for Cl− is −381 kJ mol−1. So total hydration energy −4665 + 3 × −381 = −5808 kJ mol−1 is greater than ionization energy.Similar Questions
