What is eudiometer?

An eudiometer is a laboratory device used to measure the volume changes that take place in a chemical reaction. It typically consists of a graduated glass tube that is partially filled with a gas, such as hydrogen or oxygen, and immersed in a liquid, such as water or mercury.

When a chemical reaction occurs in the eudiometer, the volume of gas inside the tube will either increase or decrease, depending on the nature of the reaction. By measuring the change in volume, scientists can determine the stoichiometry of the reaction and calculate the amount of reactants consumed and products formed.

Eudiometers are commonly used in experiments involving gases, such as studying the stoichiometry of gas-phase reactions or determining the composition of gas mixtures. They are also used in educational settings to demonstrate the principles of gas laws and chemical reactions.
