What is acid rain 1 marks answer?
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.
What is acid rain question?
Definition: Acid rain, also known as acid deposition, is a general phrase that refers to any type of precipitation that contains acidic components, such as sulfuric or nitric acid, and falls on the ground in wet or dry forms from the atmosphere. This can include acidic rain, snow, fog, hail, or even dust.
How does acid rain effect leaves?
At high elevations, acidic fog and clouds might strip nutrients from trees’ foliage, leaving them with brown or dead leaves and needles. The trees are then less able to absorb sunlight, which makes them weak and less able to withstand freezing temperatures.
How can you make acid rain?
Fill a small container with distilled water. The exact amount isn’t important, but one cup of water should be sufficient. Using the eyedropper, add some sulfuric acid to the water, stir, and check the pH with the pH meter. Keep adding sulfuric acid and stirring until the water has a pH around 4.0.

What is acid rain made of?
Acid rain describes any form of precipitation that contains high levels of nitric and sulfuric acids. It can also occur in the form of snow, fog, and tiny bits of dry material that settle to Earth. Normal rain is slightly acidic, with a pH of 5.6, while acid rain generally has a pH between 4.2 and 4.4.
What is the color of acid rain?
