In solid state as well as in solution of non-polar solvents such as benzene, aluminium chloride exists as dimer, A l 2 C l 6 . When it dissolved in water, it gives
Options
- AA l 3 + + 3 C l -
- B[ A l ( H 2 O ) 6 ] 3 + + 3 C l -
- C[ A l ( O H ) 6 ] 3 - + 3 H C l
- DA l 2 O 3 + 6 H C l
Correct answer
B. [ A l ( H 2 O ) 6 ] 3 + + 3 C l -
Step-by-step solution
A l 2 C l 6 + 12 H 2 O ⇌ 2 [ A l ( H 2 O ) 6 ] 3 + + 6 C l -
