Chemistry - Ionic Equilibrium

Practise 22 BITSAT previous year questions on Ionic Equilibrium, compiled from papers spanning 2010 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.

Ionic Equilibrium has been asked in 14 of the 16 years of BITSAT papers analysed (2009–2024), with 22 questions in all. 36% of them were easy, 41% moderate and 23% tough. Most of its questions came from 2012, with 3 questions that year. In the last three years (2022–2024) it had 6 questions across 4 papers, about 1.5 per paper.

The chapter's 5 topics are not weighted equally: PH of solutions (7 questions, 32%), Solubility (6 questions, 27%), and Theories of Acids and Bases (5 questions, 23%) have been asked the most. Over the last five years the most frequent topics have been Buffer solutions (2), PH of solutions (2), and Solubility (2). PH of solutions has produced the most tough questions (2).
