Anhydroug `A Cl_(3)` is covalent . From the data given below
Lattice Energy `=5137KJ//mol`
`DeltaH` hydrogen for `Al^(3+)=-4665KJ//mol`
`DeltaH` hydration for `Cl^(-)=-381KJ//mol`
Identify the correct statement.

Options

A. It will remain covalent in aqueous solution
B. The solution will consist of `Al^(3+) & Cl^(-)`
C. The solution will consist of hydrated `Al^(3+) & Cl^(-)`
D. None of these

Answer

3

Explanation

`implies" "DeltaH_("solution")=-4665-3xx381+5137lt0`
Hence `AlCl_(3)` will dissolve and solution consists of hydrated `Al^(3+)` and `Cl^(-)` ions.
