What is the Lewis acid in the following reaction?

Fe³⁺(aq) + 6 CN^-(aq) ⇄ Fe(CN)₆^3-(aq)

Fe³⁺(aq)

HCN(aq)

CN^-(aq)

Fe(CN)₆^3-(aq)

Fe(OH₃(aq)

Expert Solution

According to the definition of Lewis acid, an ion / metal centre / compound which can accept the election pair from an electron donating substance, that is known as Lewis acid. Simply Lewis acid is electron acceptor.

Now in the above example, Fe 3+ acts as Lewis acid, because it is electron deficient metal centre. H + is also a Lewis acid, and it also comes into the class of Bronsted acid.
