Phenol acts both as antiseptic and disinfectant.T/F

Answer

**Step-by-Step Solution:**

1. **Understanding Phenol**: Phenol is an organic compound consisting of a hydroxyl group (-OH) attached to a benzene ring. Its chemical structure plays a significant role in its properties.

2. **Antiseptic Properties**: Phenol acts as an antiseptic when applied to living tissues. Antiseptics are substances that prevent the growth of microorganisms on living tissues. Phenol has antimicrobial properties, making it effective in treating cuts, wounds, and infections by preventing inflammation and promoting healing.

3. **Disinfectant Properties**: Phenol also functions as a disinfectant. Disinfectants are used on non-living surfaces to eliminate microorganisms. Phenol can be used for cleaning purposes in homes and for sterilizing surgical instruments in medical settings.

4. **Concentration Matters**: The effectiveness of phenol as an antiseptic or disinfectant depends on its concentration. A diluted solution (0.1% to 0.2%) is effective as an antiseptic, while a more concentrated solution (around 1%) is used as a disinfectant.

5. **Conclusion**: Since phenol can act both as an antiseptic and a disinfectant depending on its concentration, the statement in the question is true.

**Final Answer**: True
