When baking soda (NaHCO3) and vinegar (HC2H3O2) react, one of the products is carbonic acid (H2CO3). Carbonic acid rapidly decom
poses into carbon dioxide gas (CO2) and water (H2O), which are two of the compounds found in volcanic gas. In this experiment, you'll measure how these gases alter temperature. Before starting the experiment, predict how you think the presence of CO2 and H2O will affect temperature. Explain your reasoning.
Carbon dioxide and water vapour concentrations will lead to change in temperatures.
Explanation:
Most of the common volcanic gases include carbon dioxide, sulphur dioxide and hydrogen sulphide along with small quantities of volatile compound and elements present such as hydrogen, helium and chloride etc.
The carbon dioxide and water vapour alter the temperature During the experiment the concentration of carbon dioxide goes up and the temperature goes down. Thus volcanic eruption often leads to global cooling.
