Question

Name the following:

Salt referred to as Bengal saltpetre.

Answer 1

• Saltpetre or saltpetre are naturally occurring nitrate salts found in rocks and soil in the form of powder and used in fertilisers and gunpowder. Because nitrates are a nitrogen source, saltpetre is also known as nitre. Saltpetre is known in Latin as "sal petrae," which translates as "rock salt."
• Because potassium nitrate $\left({\mathrm{KNO}}_3\right)$ is a nitrate salt, it is also known as saltpetre of nitre.
• As potassium nitrate is mostly found in Bengal and Bihar, it is referred to as Bengal saltpetre.
• As a result, potassium nitrate $\left({\mathrm{KNO}}_3\right)$ is also known as Nitre and Bengal saltpetre.
