Freezing Point Depression

JEE Main asked Freezing Point Depression 16 times in 16 of the 108 shifts Lumi analysed, in 2020, 2021, 2022 and 2024. It belongs to Colligative Properties, in Solutions (Chemistry). The longest wait between two years asking it was 2 years. In 2020, 2021, 2022 and 2024 it came in more than one shift of the same year.
