Vietnam team competes in the 2025 International Chemistry Olympiad.
In the medal tally, the Vietnamese team ranked equal with the Chinese and American teams in terms of gold medals.
This is also the first time in history that the Vietnamese team has won 4 gold medals at the ICHO competition. This year's achievements of the Vietnamese team continue the impressive achievements at ICHO competitions in recent years. With a total of 24 contestants participating from 2020-2025, the Vietnamese team excellently won 24/24 medals, including 21 gold medals and 3 silver medals.
The ICHO exam consists of a theory test and a practical test, each lasting 5 hours.
At ICHO 2025, the practical exam requires candidates to master basic to advanced experimental skills, such as synthesizing and analyzing complexes, identifying amino acids, identifying organic compounds using thin layer chromatography techniques, titration, and UV-Vis absorption spectroscopy. This exam requires precision, logical thinking, and proficient laboratory operations.
Meanwhile, the theoretical exam revolves around environmental issues, technology or applications of chemistry in life such as: seawater desalination, solar energy, tennis balls, lanterns ... requiring candidates to apply comprehensive knowledge and critical thinking to solve problems. The structure of this year's exam is considered creative, close to real life but still ensures scientific depth.
