Abstract
The design and use of a buret apparatus for CO2 gas capture and mass determination are described. The derivation of a comprehensive equation to determine the CO2 mass and percent carbonation of the material is outlined. Experimental factors such as temperature and pressure, including elevation effects, and apparatus parameters are discussed and incorporated into one general equation. The experimental system and calculations apply concepts of the ideal gas law and fluid mechanics. This approach, which may be adapted to the determination of the gas content of other gas evolving materials, uses relatively cheap and readily available components in the chemistry laboratory.
