Chemistry - Practical Chemistry
Practise 12 BITSAT previous year questions on Practical Chemistry, compiled from papers spanning 2009 to 2021. 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.
Practical Chemistry has been asked in 11 of the 16 years of BITSAT papers analysed (2009–2024), with 12 questions in all. 17% of them were easy, 50% moderate and 33% tough. Most of its questions came from 2019, with 2 questions that year.
The chapter's 3 topics are not weighted equally: Preliminary Tests (6 questions, 50%), Radicals (4 questions, 33%), and Identification of Basic Radicals (2 questions, 17%) have been asked the most. Preliminary Tests has also led over the last five years, with 1 question. Preliminary Tests has produced the most tough questions (2).
