👉 A carbacidometer is a type of device used to measure the concentration of carbon dioxide in air. It consists of a tube with a glass capillary that has been coated with a substance called a "carbonic acid" or "carbide." When carbon dioxide gas is passed through the capillary, it reacts with the carbide and produces carbonic acid, which then dissolves into solution. The concentration of carbon dioxide in air can be measured by comparing the volume of carbonic acid that
