Chemistry - Redox Reactions

Practise 19 BITSAT previous year questions on Redox Reactions, compiled from papers spanning 2009 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty BITSAT tests.

Redox Reactions has been asked in 12 of the 16 years of BITSAT papers analysed (2009–2024), with 19 questions in all. 37% of them were easy, 53% moderate and 11% tough. Most of its questions came from 2024, with 3 questions that year. In the last three years (2022–2024) it had 3 questions across 2 papers, about 1.5 per paper.

The chapter's 6 topics are not weighted equally: Oxidation and Reduction Reactions (7 questions, 37%), Equivalence concept (4 questions, 21%), and Oxidation number (3 questions, 16%) have been asked the most. Over the last five years the most frequent topics have been Balancing of redox reactions (2), Types of redox reactions (2), and Oxidation and Reduction Reactions (1). Equivalence concept has produced the most tough questions (1).
