== Baltic Chemistry Olympiad ==
The Baltic Chemistry Olympiad (BChO) is an annual competition that gathers selected chemistry students from [[Estonia]], [[Latvia]], and [[Lithuania]]. This event allows students to meet and solve challenging chemistry problems. It promotes values like Openness, Fairness, and Unity.
=== History ===
The competition was first proposed by Gunārs Rumba, who was the organiser of the Latvian Chemistry Olympiad. The first BChO happened in [[Riga]], Latvia, from May 3 to May 5, 1993. Each year, a different one of the three countries hosts the event.
BChO is among a few international chemistry olympiads with a significant history: International (since 1968), Mendeleev (since 1992), Ibero-American (since 1996). Most importantly, the problems of all BChO theoretical exams are available in English. Thus, not only BChO is a regionally important event, but also a significant source of training problems for the chemistry community.
=== Format and Participation ===
20 students participate in every BChO – 6 from each country and 2 more from the host country. Usually, there are 6 theoretical tasks (2 tasks are prepared by each country) worth 60–70 points and 2 practical tasks worth 30–40 points (prepared by the host country) for a total of 100 points. The jury includes representatives from each country, so mentors from all three countries work together to prepare the theoretical problems.
=== Selection and Impact ===
Students are chosen through a system that involves school teachers, [[Lecturer|university lecturer]]<nowiki/>s, and former participants. This competition is very important for preparing and selecting the national teams for the [[International Chemistry Olympiad]].
=== Problems ===
The Baltic Chemistry Olympiad emphasizes aspects of chemistry typical for leading universities in the [[Baltic states|Baltic]] countries. For example, the [[University of Tartu]] focuses on chemical devices, including different types of batteries, [[Internal combustion engine|internal combustion engines]], and fuel cells. Likewise, scientists from the Latvian Institute of Organic Synthesis have prepared problems on the synthesis of organic compounds.
The Olympiad covers many topics, including:
* Analytical Chemistry: Determining unknown compounds in puzzle-like questions.
* Applied Chemistry: Overviewing real-life chemistry, such as batteries and industrial processes.
* Biochemistry: Dealing with biological molecules like peptides and enzymes.
* Calculations related to chemistry, like titrations.
* Crystallography: Examining crystal structures and related theories.
* Electrochemistry: Working with reactions that involve applied potentials.
* Equilibrium: Dealing with equilibrium in chemical reactions.
* Inorganic Chemistry: Various topics in inorganic chemistry.
* Chemical Kinetics: Working with various aspects of kinetics.
* Mechanisms: Looking at the steps of chemical reactions.
* Radiochemistry: Focusing on radioactive substances and nuclear chemistry.
* Spectroscopy: Anything related to spectroscopy.
* Stereochemistry: Understanding how molecules are arranged in space.
* Structural Chemistry: Looking at how atoms are connected in molecules.
* Synthesis: Building organic compounds from simpler ones.
* Thermodynamics: Balancing energy and heat in chemical reactions.
