What color is the sky when it rains acid? Does acid rain contain sulfur dioxide?

Acid rain is mainly composed of sulfur dioxide, nitrogen oxides and other acidic gases produced by the combustion of fossil fuels. After complex atmospheric chemical reactions, they are absorbed and dissolved by rainwater. Acid rain is also called red rain. Its pH value is slightly acidic. If it is so for a long time, it will corrode steel products and cause slight damage to human skin and mucous membranes. Plastics will also be dissolved when acid rain falls. It depends on whether the harm is serious.

What color is the sky when it rains acid rain?

The sky is red during acid rain.

Acid rain is also called red rain. Acid rain refers to industrial pollutants such as sulfur dioxide and hydrogen sulfide in the air, which dissolve into water vapor to form a small amount of sulfuric acid molecules and condense into raindrops. Its pH value is slightly acidic. If it continues for a long time, it will corrode steel products and cause slight damage to human skin and mucous membranes. Plastics will also be dissolved when acid rain falls.

The rain is colored because tornadoes or hot air currents carry colored soil or pollen to high altitudes, where it mixes with water vapor and falls as colored rain.

Does acid rain contain sulfur dioxide?

Acid rain is precipitation with a pH value of less than 5 or 6. Including rain and snow, the acidic component of acid rain is mainly sulfuric acid, and it also contains small amounts of nitric acid and hydrochloric acid.

Acid rain is mainly composed of acidic gases such as sulfur dioxide and nitrogen oxides produced by the combustion of fossil fuels. After complex atmospheric chemical reactions, they are absorbed and dissolved by rainwater.

What pollution is the main source of acid rain?

The acid rain in my country is mainly caused by sulfur dioxide gas, while the acid rain in foreign countries is nitric acid type, which is caused by nitrogen oxides.

Sulfur dioxide in the air mainly comes from the combustion of sulfur-containing coal or the smelting of sulfur-containing minerals.

The harm of acid rain:

1. Harm to aquatic systems, resulting in loss of fish and other biological communities, changes in the cycle of nutrients and toxins, dissolution of toxic metals into the water and entry into the food chain, resulting in species reduction and productivity decline.

2. The harm to terrestrial ecosystems is mainly manifested in soil and plants. The impact on soil includes inhibiting the decomposition of organic matter and the fixation of nitrogen, leaching nutrients such as calcium, magnesium, and potassium, and impoverishing the soil. For plants, acid rain damages new leaf buds, affects their growth and development, and leads to the degradation of forest ecosystems.

3. Impact on the human body. First, heavy metals such as mercury and lead enter the human body through the food chain, inducing cancer and Alzheimer's disease. Second, acid mist invades the lungs, inducing pulmonary edema or leading to death. Third, long-term living in an environment containing acid precipitation induces excessive production of oxidized lipids, leading to an increased probability of diseases such as arteriosclerosis and myocardial infarction.

4. Corrosion to buildings, machinery and municipal facilities.
