Q & A

What is green chemistry?

Green chemistry, also known as sustainable chemistry, is the effort to design chemical processes and products in a way that reduces or eliminates the use and formation of hazardous substances. It focuses on environmentally friendly chemical practices.

Why is green chemistry important?

Green chemistry is crucial because many chemical products and processes can have harmful impacts on both the environment and human health. By using green chemistry principles, these negative effects can be minimized or eliminated, leading to safer, more sustainable practices.

Can you give an example of a harmful chemical reaction in daily life?

One example is the incomplete combustion of fuel, such as Pertalite or Pertamax. Incomplete combustion can produce harmful substances like carbon dioxide (CO2), carbon monoxide (CO), and other pollutants that can contribute to air pollution and health problems.

What is the chemical process involved in rusting of iron?

The rusting of iron occurs when iron reacts with oxygen and water, forming iron oxide. This process leads to the degradation of the iron, making it weaker and more brittle.

Are all chemical reactions dangerous?

No, not all chemical reactions are dangerous. For example, photosynthesis in plants, where CO2 and H2O are converted into glucose (C6H12O6), is a natural, beneficial chemical reaction that supports life on Earth.

What are some of the negative impacts of harmful chemical reactions?

Harmful chemical reactions can lead to negative environmental impacts such as pollution, deforestation, fires, and the creation of waste products like plastics that are difficult to decompose.

What are the 12 principles of green chemistry?

The 12 principles of green chemistry include waste prevention, good atom management, safer chemical synthesis, safer chemical design, energy efficiency, reduction of unnecessary derivatives, safe procedures for accident prevention, real-time pollution prevention, designing products that are easily decomposed, using catalysts, renewable raw materials, and using safer solvents and materials.

How can green chemistry be applied to paper production?

In paper production, green chemistry can be applied by replacing harmful bleaching agents like caustic soda (NaOH) with safer alternatives such as hydrogen peroxide (H2O2) and catalysts, making the process more efficient and environmentally friendly.

What is the importance of renewable energy in green chemistry?

Renewable energy sources like solar power are critical in green chemistry because they help reduce reliance on fossil fuels, which contribute to greenhouse gas emissions and pollution. Solar energy, being low-carbon and sustainable, supports eco-friendly chemical processes.

What is the significance of using CO2 in dry cleaning?

Using liquid CO2 as a solvent in dry cleaning is significant because it is a safer, environmentally friendly alternative to traditional carcinogenic solvents like chlorofluorocarbons (CFCs). This method reduces harmful chemical exposure and is a better practice for both the environment and public health.
