Question

acidity of soil can be reduced by adding
(a)formic acid
(b)vinegar
(c)citric acid
(d)slaked acid​

Answer 1

Explanation:

Soil acidity can be corrected easily by liming the soil, or adding basic materials to neutralize the acid present. ... As lime dissolves in the soil, calcium (Ca) moves to the surface of soil particles, replacing the acidity. The acidity reacts with the carbonate (CO3) to form carbon dioxide (CO2) and water (H2O).
