Homogeneous mixture is formed by mixing

Options

A. phenol and water
B. iron filing and sand
C. silver chloride and water
D. ethanol and water

Answer

To answer the question "Homogeneous mixture is formed by mixing," we need to understand the definition of a homogeneous mixture and provide examples.

### Step-by-Step Solution:

1. **Definition of Homogeneous Mixture**:
A homogeneous mixture is a mixture in which the composition is uniform throughout. This means that the solute and solvent are completely soluble in each other, resulting in a single phase.

2. **Examples of Homogeneous Mixtures**:
- **Ethanol and Water**: Ethanol is a lower alcohol, and it is completely soluble in water, forming a homogeneous mixture.
- **Salt and Water**: When salt is dissolved in water, it forms a homogeneous solution where the salt is evenly distributed.
- **Sugar and Water**: Similar to salt, sugar dissolves completely in water, creating a uniform mixture.

3. **Non-Examples of Homogeneous Mixtures**:
- **Phenol and Water**: Phenol does not completely dissolve in water, leading to a non-homogeneous mixture.
- **Iron Filings and Sand**: When mixed, iron filings and sand do not form a uniform mixture; they remain separate, hence it is a heterogeneous mixture.
- **Silver Chloride and Water**: Silver chloride is not soluble in water, so it does not form a homogeneous mixture.

4. **Conclusion**:
Therefore, a homogeneous mixture can be formed by mixing substances like ethanol and water, where the components are completely miscible and form a single phase.
