Give one test to distinguish whether the given emulsion is oil in water type or water in oil type emulsion.

Explanation

To distinguish whether a given emulsion is of the oil-in-water type or the water-in-oil type, we can perform a simple test known as the **dilution test**. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Understand the Types of Emulsions**:
- **Oil-in-Water (O/W)**: In this type of emulsion, oil droplets are dispersed in water. Water is the continuous phase.
- **Water-in-Oil (W/O)**: In this type, water droplets are dispersed in oil. Oil is the continuous phase.
