Question

Describe and explain the importance of controlling acidity in the environment (air, water and soil).​

Answer 1

Answer:

Soil: Soil is used to grow crops, so it is important for it to be neutral. If it happens to be too alkaline or acidic, the crops tend to grow poorly. Acidity is usually the problem for soil, so a base can help neutralise it. Bases include limestone, slaked lime, or quick lime (more on that later!).

Water: Factory waste is often acidic, and it can leak into water. To prevent this from happening, it needs to be neutralised. Again, slaked lime is used for this.  

Air: Burning fossil fuels releases gases into the air, such as nitrogen oxides and sulphur dioxide. They react with water and air, leading to acid rain. As you can tell by the name, it's not that great; it causes buildings to erode and will negatively affect soil and water.
