12 Plants absorb several ions and water from soil. For this reason, it is necessary for the soil to have a p“ value at the range of 6.0 – 8.0. Again, if the p“ is less than 3.0 or greater than 10, then the beneficial microbes of the soil die. Normally rainwater is slightly acidic, its p# value is 5.5. During thunderstorm nitrogen and oxygen of air react to form nitric oxide, which is oxidized to form nitrogen-dioxide. This nitrogen-dioxide reacts with water vapor and forms nitrous acid and nitric acid. Acid-rain occurs because of it. 2NO2+ H2O → HNO2+HNO3 Examination of soil in a region of Rajshahi revealed that its p" value was 6.43. Nitrogen-dioxide is formed in the air because of thunderstorms, and its concentration is 0.297 ppm. What will be the difference between the pH value of the soil after rain and the lowest standard p" value ?
