before
Because there have been few attempts, thus far, to quantify the consequences for global carbon dioxide emissions, our group has decided to perform our own experiment over the next six months to measure and track carbon dioxide emissions in our local region.
during
Every Monday, we will capture a sample of air from the top of our reservation in a 100 ml sealed glass vessel. In this container, we will have 30 grams of potassium hydroxide, KOH, to ensure that it is the excess reactant in this experiment. Carbon dioxide and potassium hydroxide should react to form a precipitate, potassium bicarbonate of KHCO3. This precipitate should capture the carbon dioxide in our sample, and by weighing this sample of solid, we can perform some basic stoichiometry and roughly estimate the levels of CO2 in our region’s air.
after
After tracking this data, we hope to compare the results of the experiment to past historical dioxide outputs. We will be performing a One-Sample T-Test for Mean Difference to see if there is convincing evidence of a decrease in carbon dioxide. We predict that during these months of reduced use of factories and industrial centers, the carbon dioxide levels will be dramatically lower compared to levels in 2018 and 2019.
