Aluminium chloride exists as a dimer, Al_{2} Cl_{6}, in solid state as well as in solutions of non-polar solvents such as benzene. When dissolved in water, it gives:

Solution & Step-by-step Explanation

In non-polar solvents, AlCl_{3} remains dimeric. When added to water, the high hydration energy of Al^{3 +} breaks the dimer and the coordinate-covalent bonds to form a hydrated complex ion [Al (H_{2} O)_{6}]^{3 +} and chloride ions.

Try it yourself before checking the explanation above.

Aluminium chloride exists as a dimer, Al_{2} Cl_{6}, in solid state as well as in solutions of non-polar solvents such as benzene. When dissolved in water, it gives:

Al^{3 +} + 3 Cl^{-}

Al_{2} O_{3} + 6 HCl

[Al (OH)_{6}]^{3 -}

[Al (H_{2} O)_{6}]^{3 +} + 3 Cl^{-}
