Q1: The fertiliser plant getting hydrogen by electrolysis of water is situated at

ANS:B - Nangal

Nangal is a town located in the Rupnagar district of Punjab, India. It is known for its significance in the realm of industrial development, particularly in the fertilizer industry. One of the key features of Nangal is the presence of a major fertilizer manufacturing complex operated by the National Fertilizers Limited (NFL). The NFL Nangal complex is one of the oldest and largest fertilizer plants in India. It was established in the 1950s as part of India's efforts to achieve self-sufficiency in food production through the promotion of agricultural inputs such as fertilizers. The Nangal fertilizer complex is strategically located near the Bhakra Dam reservoir, which provides ample water supply for industrial processes. The complex primarily produces urea, a nitrogenous fertilizer crucial for promoting crop growth and increasing agricultural productivity. One notable aspect of the Nangal fertilizer complex is its use of hydrogen obtained through the electrolysis of water. Hydrogen is a key raw material in the production of ammonia, which is a precursor to urea fertilizer. Through the electrolysis process, water (H2O) is split into hydrogen (H2) and oxygen (O2) using an electric current. The hydrogen generated in this process is then utilized in the synthesis of ammonia, an essential step in urea production. Overall, the NFL Nangal complex plays a vital role in meeting the fertilizer requirements of farmers in Punjab and other regions of India, contributing to the country's agricultural development and food security goals.
