Chemistry - Ionic Equilibrium

Practise 30 KCET previous year questions on Ionic Equilibrium, compiled from papers spanning 2007 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty KCET tests.

Ionic Equilibrium has been asked in 15 of the 20 years of KCET papers analysed (2007–2026), with 30 questions in all. 37% of them were easy, 40% moderate and 23% tough. Most of its questions came from 2013, with 4 questions that year. In the last three years (2024–2026) it had 2 questions across 3 papers, about 0.7 per paper.

The chapter's 5 topics are not weighted equally: PH of solutions (16 questions, 53%), Theories of Acids and Bases (5 questions, 17%), and Buffer solutions (4 questions, 13%) have been asked the most. PH of solutions has also led over the last five years, with 2 questions. PH of solutions has produced the most tough questions (5).
