Consider the following statements regarding the Formaldehyde: It is a ...
Formaldehyde
- Statement 1: It is a colourless pungent gas.
- Statement 2: It is used as a preservative in food industries.
Formaldehyde is indeed a colourless gas with a pungent odor. It has the chemical formula CH2O and is the simplest aldehyde. It is highly reactive and often used as a precursor to other chemicals.
Formaldehyde is not commonly used as a preservative in the food industry. While it does have preservative properties, its use in food preservation is limited due to its toxicity and potential health risks. However, it is sometimes used in very small quantities in certain food products, such as smoked meats, to prevent bacterial growth.
Explanation
Based on the above analysis, it can be concluded that both statements 1 and 2 are correct.
Formaldehyde is a colourless pungent gas widely used in various industries for its versatile properties. Here are some key points about formaldehyde:
- Formaldehyde is used in the production of resins, plastics, textiles, and coatings. It is a key ingredient in the manufacturing of urea-formaldehyde resins, which are used in products like particleboard, plywood, and insulation materials.
- It is also used as a disinfectant and preservative in certain products, such as cosmetics, shampoos, and household cleaning agents. However, its use as a preservative in the food industry is limited.
- Formaldehyde is considered a hazardous substance and can cause various health issues when inhaled or absorbed by the body. Prolonged exposure to formaldehyde can lead to respiratory problems, eye irritation, and even cancer.
- Due to its toxicity, formaldehyde is regulated by various health and safety agencies, and strict guidelines are in place to limit its use and exposure in certain industries.
In conclusion, formaldehyde is a colourless pungent gas with various industrial applications. While it is not commonly used as a preservative in the food industry, it does have limited applications in certain food products. However, its use in food preservation is minimal due to its potential health risks.

Consider the following statements regarding the Formaldehyde: It is a ...
Recently, the Nanomaterials and Nanoelectronics Laboratory, Department of Physics, Guwahati University, Assam has developed a cost-effective formalin sensor that can effectively detect the presence of formalin in adulterated fishes.
- Materials used: Tin oxide-reduced graphene oxide composite (rGO- SnO2).
- While reduced graphene oxide (rGO) has been used to detect various toxic gases and VOCs, tin oxide (SnO2) has been extensively investigated for formaldehyde detection in pristine form and by incorporating it with various compounds, including graphene, due to its high stability and high sensitivity toward low concentrations of formaldehyde.
- Process: The Graphene oxide (GO) was processed through wet chemical approach and tin oxide-reduced graphene oxide composite (rGO- SnO2) was synthesized by hydrothermal route followed by calcination of the obtained product.
- They found that the sensor made of tin oxide decorated reduced graphene oxide effectively sensed formaldehyde vapor at room temperature.
- The sensor shows long-term stability with a low detection limit.
- A new low-cost sensor made of metal oxide nanoparticles reduced graphene oxide composite can detect formalin adulteration in fishes at room temperature in a non-invasive way.
- The research for this supported by DST-PURSE (Promotion of University Research and Scientific Excellence).
What is Formaldehyde?
- It is a colourless, pungent gas that is used in a variety of industrial processes, including as a preservative in some foods, commonly in fish in developing countries.
Hence both statements are correct.
