Depending upon concentration , phenol can be used both as an _______ as well as a _______

Answer

To answer the question regarding the uses of phenol depending on its concentration, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Phenol**: Phenol is a chemical compound that has antiseptic and disinfectant properties. It is important to know that its effectiveness depends on its concentration.

2. **Defining Antiseptic**: An antiseptic is a substance that can be applied to living tissues to reduce the possibility of infection, sepsis, or putrefaction. It is safe for use on skin and wounds.

3. **Defining Disinfectant**: A disinfectant, on the other hand, is a chemical agent used to destroy or inhibit the growth of harmful microorganisms on inanimate objects. Disinfectants are not safe for application on living tissues.

4. **Concentration of Phenol**:
- **As a Disinfectant**: Phenol can be used as a disinfectant when it is in a concentration of about 1%. This concentration is effective for killing bacteria and other pathogens on surfaces.
- **As an Antiseptic**: When phenol is diluted to a concentration of about 0.2%, it can be used as an antiseptic. This lower concentration is safe for application on skin and wounds.

5. **Conclusion**: Based on the above information, we can conclude that depending on concentration, phenol can be used both as an **antiseptic** and as a **disinfectant**.

### Final Answer:
Phenol can be used both as an **antiseptic** as well as a **disinfectant**.
