What is acid rain and how it is formed?
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.
Is there acid rain in carbon cycle?
Carbon emissions have been linked to acid rain, which falls into oceans, lakes and rivers. … Acid rain is caused by industrial emissions of sulfur dioxide and nitrogen oxides (which form much stronger acids when equilibrated in rainwater).
What is acid rain How does it form Why is it bad?
and (4) may cause harmful effects on soil, forests, streams, and lakes. 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.
What contributes the most to acid rain?
Sulfur dioxide (SO2) and nitrogen oxides (NOx) released into the air by fossil-fuel power plants, vehicles and oil refineries are the biggest cause of acid rain today, according to the EPA. Two thirds of sulfur dioxide and one fourth of nitrogen oxide found in the atmosphere come from electric power generators.
How is acid rain formed 8?
Answer: Pollutants like sulphur dioxide and nitrogen dioxide liberated into the air by industries reacts with water vapour in air to form sulphuric acid and nitric acid. These acids come down as rain, called acid rain.
How is acid deposition formed?
Acid deposition, commonly known as acid rain, occurs when emissions from the combustion of fossil fuels and other industrial processes undergo complex chemical reactions in the atmosphere and fall to the earth as wet deposition (rain, snow, cloud, fog) or dry deposition (dry particles, gas).
Can acid rain burn your skin?
Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this; it is never acidic enough to burn your skin. Rain is always slightly acidic because it mixes with naturally occurring oxides in the air.
Why does acid rain reduce photosynthesis?
Acid rain at pH 4.0 or less decreased leaf water content, destroyed chloroplast structure, inhibited the expression of six chloroplast ATP synthase subunits, decreased chloroplast ATP synthase activity, and reduced photosynthesis and plant growth.
