The correct Answer is:
To solve the question regarding which factory's effluent is most likely responsible for lowering the pH of river water to an acidic range of 3.5-4.5, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding pH Levels**: - The pH scale ranges from 0 to 14. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic. - Since the river water has a pH of 3.5-4.5, it indicates that the water is acidic. 2. **Analyzing the Options**: - We have several factories discharging effluents: soap and detergent factory, lead battery manufacturing factory, plastic cup manufacturing factory, and alcohol distillery. 3. **Evaluating Each Factory's Effluent**: - **Soap and Detergent Factory**: - Soaps and detergents are typically basic in nature. Therefore, they would not contribute to acidity. This option can be eliminated. - **Lead Battery Manufacturing Factory**: - Lead batteries use sulfuric acid as an electrolyte, which has a pH of around 2. This indicates a strong acidic nature, which could significantly lower the pH of the river water. This option is a strong candidate. - **Plastic Cup Manufacturing Factory**: - Plastics are generally neutral or basic and do not contribute to acidity in water. This option can be eliminated. - **Alcohol Distillery**: - Alcohol can act as a weak acid or a weak base, but it generally does not significantly lower pH levels. Therefore, this option is less likely to be the cause of the acidic pH. 4. **Conclusion**: - After evaluating all the options, the factory most likely responsible for lowering the pH of the river water to an acidic level is the **Lead Battery Manufacturing Factory**. ### Final Answer: The effluents from the **Lead Battery Manufacturing Factory** are the most likely cause for lowering the pH of the river water. ---
