Limewater practical
NettetIn this experiment we will investigate the carbon dioxide levels of inhaled and exhaled air. We use limewater to test for the presence of carbon dioxide.Webs... Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate. This … Se mer Keep an eye on less mature students who might be tempted to suck rather than blow through the filtrate. The results expected are as follows: This set of experiments involves a variety of important reactions and types of reactions, … Se mer
