Chemistry experiment. Student recording the results of an experiment. The experiment involves bubbling the gas produced from the reaction at right through limewater (saturated calcium hydroxide solution). If the limewater turns cloudy, the gas is carbon dioxide. A typical reaction that produces carbon dioxide is the reaction of calcium carbonate with an acid.
