AlCl 3 in water at pH

Question

AlCl 3 in water at pH < 7 forms (A) tetrahedral Al ( OH )4- ions (B) octahedral Al ( OH )63- ions (C) square planar Al ( OH )4- ions (D) Octahedral Al ( OH 2)63+ ions

Tardigrade Admin · Accepted Answer

AlCl 3 form [ Al ( H 2 O )6]3+ in water due to acidic medium ( pH < 7). AlCl 3+6 H 2 O longrightarrow [ Al ( H 2 O )6]3++3 Cl ominus

Q. $A lC l_{3}$ in water at $p H < 7$ forms

tetrahedral $A l (O H)_{4}^{-}$ ions

octahedral $A l (O H)_{6}^{3 -}$ ions

square planar $A l (O H)_{4}^{-}$ ions

Octahedral $A l (O H_{2})_{6}^{3 +}$ ions

$A lC l_{3}$ form $[A l (H_{2} O)_{6}]^{3 +}$ in water due to acidic medium $(p H < 7)$ .

$A lC l_{3} + 6 H_{2} O ⟶ [A l (H_{2} O)_{6}]^{3 +} + 3 C l^{⊖}$
