- Neutral solution is a solution whose pH is close to 7. They prefer remaining at a perfect balance.Usually a neutral solution is neither acidic nor basic. It doesn't imply that the neutral solution lacks charged ions.
- Natural Indicator is a type of indicator that can be found naturally and can determine whether the substance is an acidic substance or a basic substance. Some examples of natural indicators are red cabbage, turmeric, grape juice, turnip skin, curry powder, cherries, beetroots, onion, tomato, etc.
- Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.
- 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.
- While a small portion of the SO2 and NOX that cause acid rain is from natural sources such as volcanoes, most of it comes from the burning of fossil fuels.

Consider the following assertions:1. The solutions which do not chang...
Explanation:
Let's analyze each assertion one by one:
Assertion 1: The solutions which do not change the colour of either red or blue litmus are known as neutral solutions.
This assertion is correct. A neutral solution is one that has a pH value of 7, which means that it is neither acidic nor basic. Litmus paper is a commonly used indicator to determine the acidic or basic nature of a solution. When a solution does not change the color of either red or blue litmus paper, it indicates that the solution is neutral.
Assertion 2: Turmeric, litmus, china rose petals are some of the naturally occurring indicators.
This assertion is also correct. Natural indicators are substances that can be found in nature and are used to determine the acidic or basic nature of a solution. Turmeric, litmus, and china rose petals are examples of such natural indicators. Turmeric turns reddish-brown in acidic solutions and yellow in basic solutions. Litmus paper turns red in acidic solutions and blue in basic solutions. China rose petals change color in the presence of acids or bases.
Assertion 3: When acid content is high in rainwater, then it is called acid rain.
This assertion is correct. Acid rain refers to rainwater that has a high concentration of acids, particularly sulfuric acid and nitric acid. Acid rain is formed when pollutants such as sulfur dioxide and nitrogen oxides are released into the atmosphere through human activities, primarily the burning of fossil fuels. These pollutants combine with water vapor in the air to form acids, which then fall back to the Earth as rain. Acid rain can have detrimental effects on the environment, including damage to plants, soil, and aquatic ecosystems.
Conclusion:
All three assertions are correct:
- Assertion 1 defines neutral solutions correctly.
- Assertion 2 provides examples of natural indicators.
- Assertion 3 accurately describes acid rain.
Therefore, the correct answer is option 'D', i.e., 1, 2, and 3.
