Summary:The Solvay Process is an important route for the industrial preparation of sodium carbonate from brine and CO2. However, experiments illustrating such process are performed only in a few chemistry courses, mainly because of the difficulties to precipitate out the intermediate product NaHCO3 within the 3 or 4 hours generally available for laboratory classes. In this article we describe a method that properly simulates the Solvay process using glass apparatus that can be found in any chemistry laboratory. The good yields and purity attainable, associated with the short time (~3 hours) required to get the sodium bicarbonate, account for the suitability of our method for chemistry or chemical engineering undergraduate students laboratory classes.
