A scrubber can remove gaseous pollutants like sulpur dioxide.

Answer

### Step-by-Step Text Solution:

1. **Understanding the Scrubber System**: A scrubber is a device used to remove pollutants from industrial exhaust gases. It is designed to clean the air by removing harmful substances.

2. **Function of Scrubbers**: Scrubbers work by utilizing a chemical reaction. They often use a sorbent (a material that absorbs or adsorbs pollutants) to interact with the gaseous pollutants.

3. **Target Pollutants**: One of the key pollutants that scrubbers target is sulfur dioxide (SO₂), which is a significant contributor to air pollution and can cause acid rain.

4. **Chemical Reaction**: In the scrubber system, sulfur dioxide reacts with the sorbent material. This reaction helps to convert sulfur dioxide into a less harmful substance, effectively removing it from the exhaust gases.

5. **Effectiveness**: Scrubbers are effective in reducing the concentration of sulfur dioxide and other acid gases in the air, making them an essential technology for controlling air pollution.

6. **Conclusion**: Therefore, it is accurate to say that scrubbers can effectively remove gaseous pollutants like sulfur dioxide from the air.
