Q6. Consider the following about Sodium Nitrite, recently seen in news.
1. It is both an oxidising and a reducing agent.
2. It is a food additive to enhance botulism.
3. It is on the World Health Organization's List of Essential Medicines.
Select the correct answer using the codes below.
1. Sodium nitrite is the inorganic compound with the chemical formula NaNO2. It is a white to slightly yellowish crystalline powder that is very soluble in water and is hygroscopic. It is a useful precursor to a variety of organic compounds, such as pharmaceuticals, dyes, and pesticides, but it is probably best known as a food additive to prevent botulism. The main use of sodium nitrite is for the industrial production of organ nitrogen compounds.
2. Sodium nitrite is well known for its role in inhibiting the growth of Clostridium botulinum (causing toxic Botulism) spores in refrigerated meats. The mechanism for this activity results from the inhibition of iron-sulphur clusters essential to energy metabolism of Clostridium botulinum.
3. World Health Organization's List of Essential Medicine contains the most important medications needed in a basic health system.
