Chemistry - Solutions

Practise 17 BITSAT previous year questions on Solutions, 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.

Solutions has been asked in 10 of the 16 years of BITSAT papers analysed (2009–2024), with 17 questions in all. 24% of them were easy, 65% moderate and 12% tough. Most of its questions came from 2024, with 4 questions that year. In the last three years (2022–2024) it had 6 questions across 5 papers, about 1.2 per paper.

The chapter's 3 topics are not weighted equally: Colligative Properties and Abnormal Molecular Masses (14 questions, 82%), Vapour pressure and raoult's law (2 questions, 12%), and Solubility and Concentration of Solutions (1 question, 6%) have been asked the most. Colligative Properties and Abnormal Molecular Masses has also led over the last five years, with 5 questions. Colligative Properties and Abnormal Molecular Masses has produced the most tough questions (2).
