Question

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

Answer 1

Answer:H20

Step-by-step 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`
