If field soil is highly acidic, what happens when lime is added to it?
Answer and explanation
Correct answer: Soil acidity decreases
Lime, commonly represented by calcium oxide or calcium hydroxide in this context, has a basic character. The governing concept is neutralisation: the basic material reacts with acidic components of soil and raises the soil pH toward a more suitable range. Therefore, option B is correct. Adding lime does not remove all water or transform soil into metal, and it cannot increase acidity.
