What will you learn in NCERT Solutions for Class 11 Chemistry Chapter 14 Environmental Chemistry?

Environmental chemistry tells you about the origin, reactions, and the effects various chemicals have on the environment. The chapter focuses on studying the environment, which is a combination of social, biological, physical, and chemical entities.

Pollution

When harmful changes occur in the environment, it affects living beings such as plants and animals. The substances which cause these changes are known as a ‘pollutants.’ Pollutants exist in all states of matter, including solid, liquid, and gas. Humans produce pollutants when they set up industries or factories and release waste byproducts into the environment. Pollutants are degradable, meaning that the various natural processes that occur in the surroundings tend to break them down. However, other pollutants degrade at a slower rate and hence, remain in the surroundings for more extended periods, adversely affecting living creatures.

For instance, substances like plastic and metal are non-degradable and thus, lie around in the environment causing more damage.

Pollution is of two types. The first type, called Natural Pollution comes from natural sources such as volcanic eruptions. And the second type, also known as human-made pollution, is the result of human activities.

The atmosphere can also become polluted due to the release of oxides of carbon such as carbon monoxide.

Environment

The four different layers of the environment include the atmosphere, hydrosphere, lithosphere, and biosphere. The atmosphere is further sub-divided into five layers. They are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

Types of Pollutants

While pollutants come in both biodegradable and non-biodegradable forms, they also form depending on their occurrence and existence. So, you have naturally occurred, and human-made pollutants also called primary and secondary pollutants.

Air Pollution

Nitrogen and Oxygen constitute the major components of the air that surrounds us. And other gases such as Argon and Carbon Dioxide make up the minor elements. Among these constituents, the oxides of Carbon, Nitrogen, and Sulphur are the primary causes of air pollution. Apart from these, other gases such as Ozone, CFC, different metals, hydrocarbons, smog, dust, and other pollutants also cause air pollution.

The significant effects of air pollution include acid rain, depletion of the ozone layer, and global warming.

Acid Rain

The acids of Nitrogen and Sulphur formed by the oxidation of the two elements is the primary cause of acid rain. Acid rains tend to occur more in industrial areas rather than in other areas and affect buildings, reducing their lifespans. They also have detrimental effects on the soil.

Depletion of the Ozone Layer

The release of chlorofluorocarbons or CFC is the primary cause for the depletion of the ozone layer that covers the earth and protects it from the harmful ultraviolet radiations. Ultraviolet radiations affect the photosynthesis process that takes place in plants.

Global Warming

Global warming is the effect of the release of gases like the oxides of carbon into the atmosphere. Due to industrialization and deforestation, the amount of carbon dioxide let out is increasing by the day. Global warming leads to the melting of ice caps, causing floods, rains, cyclones, and hurricanes, among other things. If not controlled, it is bound to affect agricultural production.
