Do `Fe(III)` salts and `Fe(II)` salts both give red colouration with dimethylglyoxime in ammonical solution. If not then which iron salt gives red colouration with dimethylglyoxime ?

Explanation

To answer the question regarding the reaction of iron salts with dimethylglyoxime in ammonical solution, we will analyze the behavior of both Fe(III) and Fe(II) salts.

### Step-by-Step Solution:

1. **Identify the Iron Salts**:
- We have two types of iron salts to consider: Fe(III) (ferric) salts and Fe(II) (ferrous) salts.

2. **Understand the Reaction with Dimethylglyoxime**:
