Chemistry - General Principles and Processes of Isolation of Metals

Practise 20 AIIMS previous year questions on General Principles and Processes of Isolation of Metals, compiled from papers spanning 2002 to 2019. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty AIIMS tests.

General Principles and Processes of Isolation of Metals has been asked in 12 of the 19 years of AIIMS papers analysed (2001–2019), with 20 questions in all. 70% of them were easy, 30% moderate and 0% tough. Most of its questions came from 2018, with 3 questions that year. In the last three years (2017–2019) it had 6 questions across 5 papers, about 1.2 per paper.

The chapter's 6 topics are not weighted equally: Extraction of Metals (7 questions, 35%), Reduction to Crude Metal (4 questions, 20%), and Minerals and ores (3 questions, 15%) have been asked the most.
