Explanation A l C l 3 produces A l 3 + and C l − ions in the solution. A l C l 3 ( s ) → A l 3 + ( a q ) + 3 C l − ( a q ) The C l − ions do not affect the p H of a water solution. A l 3 + ion react with water to form hydrated aqueous aluminum ion. A l 3 + ( a q ) + 6 H 2 O ( a q ) → [ A l ( H 2 O ) 6 ] 3 + K a value of [ A l ( H 2 O ) 6 ] 3 + is 1.0 × 10 − 5 . The equation for the equilibrium can be written as given below. [ A l ( H 2 O ) 6 ] 3 + ( a q ) + H 2 O ( l ) ⇌ A l ( H 2 O ) 5 ( O H ) 2 + ( a q ) + H 3 O + ( a q ) The acid ionization constant for the above equation can be written as given below. K a = [ A l ( H 2 O ) 5 ( O H ) 2 + ] [ H 3 O + ] [ A l ( H 2 O ) 6 3 + ] A table can be set up as given below.
