What is the formation of acid rain?

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

How does NO2 form acid rain equation?

In air, NO is oxidized to nitrogen dioxide (NO2) (Equation 4), which in turn reacts with water to give nitric acid (HNO3) (Equation 5). This acid dissociates in water to yield hydrogen ions and nitrate ions (Equation 6), lowering the pH of the solution.

What is acid rain simplified?

Acid rain is rain that is unusually acidic and highly corrosive in nature. It may be defined as “rain water having pH less than 5.6”. Acid rain can have harmful effects on plants, animals and humans. It is caused when gaseous compounds of ammonium, carbon, nitrogen, and sulphur are released into the atmosphere.

How do you calculate pH of acid rain?

Explanation: pH is an expression of the hydrogen ion concentration within a solution. Mathematically, the pH will equal −log10[H+] , or the negative logarithm of the molar concentration of hydrogen ion about the solution.

What causes acid rain Mcq?

Explanation: Acid rain is mainly caused due to a result of air pollution. Explanation: The gases of nitrogen oxides and sulphur dioxide react with the tiny droplets of water in clouds to form sulphuric and nitric acid.

What is acid rain write its effect?

When the accumulated acids are washed off a surface by the next rain, this acidic water flows over and through the ground, and can harm plants and wildlife, such as insects and fish. The amount of acidity in the atmosphere that deposits to earth through dry deposition depends on the amount of rainfall an area receives.

What is the chemical formula of nitrogen dioxide?

NO₂
Nitrogen dioxide/Formula

What is acid rain 9th class?

Acid Rain is when gases in the atmosphere combines with falling water to form acids, which fall as rain. Two gases which cause it are: Sulphur Dioxide. Nitrogen Dioxide.

What is the pH level of acid rain Mcq?

Acid rain refers to the highly acidic precipitation. Normal pH of rain is slightly acidic ~5.6 due to reaction of CO2 with rainwater. The pH of the acid rain drops below 5.6 and it becomes ~4.2 – 4.4.

What is acid rain Mcq?

Acid rain refers to the highly acidic precipitation. Normal pH of rain is slightly acidic ~5.6 due to reaction of CO2 with rainwater. The pH of the acid rain drops below 5.6 and it becomes ~4.2 – 4.4. It mostly occurs due to the presence of oxides of sulphur and nitrogen in the atmosphere.

Why is Rain naturally acidic equation?

2SO 2 (g) + O 2 (g) + 2H 2 O (I) → 2H 2 SO 4 (aq) Acid rain occurs when the pH of rain water falls between 2.0 to 5.5. This is due to the presence of sulphurous acid, sulphuric acid and nitric acid in rain water. Sources of SO2

What are the chemical reaction equations for acid rain?

Acid rain is formed when nitrogen oxides or sulfur oxides in the atmosphere react with suspended water droplets and produce acids. The chemical reaction equation for the production of acid rain resulting from sulfur oxides is: SO2 + HOH -> H2SO3. The reaction equation for acid rain produced from nitrogen oxides is: 2NO2 + HOH -> HNO2 + HNO3.

What is it the chemical equation for acid rain?

2NO 2 (g) + H 2 O (l) ==> HNO 3 (aq) + HNO 2 (g) Acidic rain is mainly caused by atmospheric pollutants of sulfur dioxide and nitrogen oxides. The chemical formula of acidic rain is dependent upon the type of acids present. Acidic rain is a complex mixture of nitrous, nitric, sulfurous and sulfuric acids which all combine to lower the pH.

Why is acid rain so bad?

The acid in acid rain drains important minerals from the leaves and the soil, and is very bad for plants, trees and agricultural land. If the soil is alkaline; when acid rain falls on it the acid becomes neutral and so the plants are not hugely affected, but it the soil is slightly acidic, it can be disastrous.
