Chemistry - Solutions

Practise 154 AP EAMCET previous year questions on Solutions, compiled from papers spanning 2003 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty AP EAMCET tests.

Solutions has been asked in 20 of the 24 years of AP EAMCET papers analysed (2001–2024), with 154 questions in all. 31% of them were easy, 55% moderate and 14% tough. Most of its questions came from 2022, with 19 questions that year. In the last three years (2022–2024) it had 51 questions across 28 papers, about 1.8 per paper.

The chapter's 4 topics are not weighted equally: Colligative Properties and Abnormal Molecular Masses (73 questions, 47%), Vapour pressure and raoult's law (48 questions, 31%), and Solubility and Concentration of Solutions (19 questions, 12%) have been asked the most. Colligative Properties and Abnormal Molecular Masses has also led over the last five years, with 37 questions. Colligative Properties and Abnormal Molecular Masses has produced the most tough questions (12).
