Question

Identify the Lewis base in this balanced equation: Fe3+ H2O Fe(H2O)63+

Answer 1

Answer:H20

Explanation:

because it is the base that contributes electrons

Answer 2

Answer : The Lewis-base in this reaction is, water $H_2O$

Explanation :

According to the Lewis acid-base theory,

Lewis acid : It is a substance that can accepts pairs of electrons to form a covalent bond.

Lewis-base : It is a substance that can donates pairs of electrons to form a covalent bond.

The given balanced equation is:

$Fe^{3+}+6H_2O\rightarrow [Fe(H_2O)_6]^{3+}$

In this reaction, $Fe^{3+}$ ion is Lewis-acid and $H_2O$ is a Lewis-base. The $H_2O$ donates electrons to $Fe^{3+}$ ion to form $[Fe(H_2O)_6]^{3+}$.

Hence, the Lewis-base in this reaction is, water $H_2O$
