Preduct that anhyrous `AICI_(3)` is covalent form the data given below, ionisation enegry for `AI = 51.37 kJ mol^(-1), Delta_(hyd) H` for `AI^(3+) =- 4665 kJ "mole"^(-1), Delta_(hyd)H` for `CI^(Theta) =- 381 kJ mol^(-1))` |
| Answer» The total hydration enegry of `AI^(3+)` and `3CI^(Theta)` ions is `DeltaH_(hyd) ={-4665 +3(-381)} kJ mol^(-1) = - 5808 kJ mol^(-1)` The enegry released is more than that required for the ionisation of `AI` to `AI^(3+)` (which is `-4665 kJ mol^(-1))` causing ionisation of `AICI_(3)` solution. Thus, the compound `AICI_(3)` becomes ionic in aqueous solution. | |
