Osmotic Pressure

JEE Main asked Osmotic Pressure 7 times in 7 of the 108 shifts Lumi analysed, in 2022, 2023, 2024 and 2026. It belongs to Colligative Properties, in Solutions (Chemistry). The longest wait between two years asking it was 2 years. In 2023 and 2024 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2022, 2023, 2024 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
