Which gases are responsible for acid rain?

Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

Is CO2 is responsible for acid rain?

Acid Rain Rain is slightly acidic because it contains dissolved carbon dioxide (CO2). Sulpher dioxide (SO2) and Nitrogen oxides (NOx) which are normally present in the air.

Is CFC responsible for acid rain?

A common example of deposition is ‘rain out’: compounds that are soluble in water can be removed from the atmosphere by precipitation. This phenomenon is responsible for acid rain. The most abundant CFCs emitted into the troposphere are CFC 11 and CFC 12.

Is methane responsible for acid rain?

These non-toxic gases, most of which occur naturally in the atmosphere and are not pollutants, include carbon dioxide, methane, CFCs, and nitrous oxide. Acid rain is caused by toxic industrial smoke containing sulphur dioxide, nitrogen oxides, and chloride.

Which gases are responsible for acid rain? – Related Questions

Why does co2 not contribute to acid rain?

Carbon dioxide reacts with water to form carbonic acid thus contributing to acid rain. So, from all these gases only carbon monoxide does not react with water to form an acid. Thus, not contributing to the acid rain, So, the correct answer is “Option C”.

Does co2 dissolve in rain?

Other significant sinks of CO2 are rainwater and soil water (Liu et al. 2010). The rainwater is highly sensitive to atmospheric changes and dissolves CO2 with other components like major ions, gases, minerals, trace elements, etc.

Does NO2 cause acid rain?

Acid rain is formed high up in the atmosphere when SO2 and NO2 combine with water and sunlight.

Is acid rain caused by air pollution?

Acid rain is one of the consequences of air pollution. Gases produced from the burning of fuels react with the oxygen in the air and water vapour, transforming into acids that fall onto the earth’s surface as rain.

What are 3 causes of acid rain?

Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

What are 5 causes of acid rain?

Human activities leading to chemical gas emissions such as sulfur and nitrogen are the primary contributors to acid rain. Factories, power generations facilities, and automobiles are the chief emitters of sulfur and nitrogen gases.

What causes acid rain Mcq?

Acid rain is caused by emissions of acidic gases like sulphur dioxide, nitrogen and carbon oxides, which react with the water molecules in the atmosphere to produce acids.

Which of the following is not an effect of acid rain Mcq?

Acid rain does not cause any environmental damages. Explanation: Acid rain cause many environmental damages. It affects the plants by removing nutrients from the soil.

Which gases are released by cars?

Pollutants produced by vehicle exhausts include carbon monoxide, hydrocarbons, nitrogen oxides, particles, volatile organic compounds and sulfur dioxide. Hydrocarbons and nitrogen oxides react with sunlight and warm temperatures to form ground-level ozone.

What is acid rain formula?

H 2O (l) + H 2CO 3 (aq) ⇌ HCO−3 (aq) + H 3O + (aq) Unpolluted rain can also contain other chemicals which affect its pH (acidity level).

Is sulphur an acid?

Sulfuric acid is a very strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H3O+) and hydrogen sulfate ions (HSO4). In dilute solutions the hydrogen sulfate ions also dissociate, forming more hydronium ions and sulfate ions (SO42).

What is called acid rain?

Acid rain is rain that has been made acidic by certain pollutants in the air. Acid rain is a type of acid deposition, which can appear in many forms. Wet deposition is rain, sleet, snow, or fog that has become more acidic than normal.

What is acid rain class 7th?

When harmful gases like sulphur dioxide and nitrogen dioxide, react with moisture present in air, they form nitric acid and sulphuric acid. These acids when dropping down on earth along with rain is called acid rain.

What is called acid rain Class 8?

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

What is an acid Class 8?

Acids are sour in taste. Acid molecules contain hydrogen ion (H+) as a main constituent. Acid reacts with metal to form hydrogen gas. Acid reacts with carbonates and liberates CO2 gas.

Is there acid rain in India?

Analysis of rainwater samples from Nagpur, Mohanbari (in Assam), Allahabad, Visakhapatnam and Kodaikanal in the decade 2001-2012 showed a pH level varying from 4.77 to 5.32, indicating that these places have actually been receiving ‘acid rain’. Rainwater with pH below 5.65 is considered acidic.

When was the first acid rain?

Acid rain was first identified in North America at Hubbard Brook in the mid-1960s, and later shown to result from long-range transport of sulfur dioxide and nitrogen oxides from power plants. Hubbard Brook research influenced national and international acid rain policies, including the 1990 Clean Air Act amendments.
