On reaction of sodium hydroxide with Iron(II) ion gives the coloured precipitate. Tell the colour .

Explanation

To solve the question about the color of the precipitate formed when sodium hydroxide reacts with Iron(II) ions, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants in this reaction are sodium hydroxide (NaOH) and Iron(II) ions (Fe²⁺).

2. **Understand the Reaction**: When sodium hydroxide is added to a solution containing Iron(II) ions, it provides hydroxide ions (OH⁻) which react with the Iron(II) ions.
