Syringe Test Experiment :: Papers

Syringe Test Experiment Formula article - Calcium carbonate + Hydrochloric acidulated = Calcium Chloride + Water + Carbon Dioxide token - CaCO + 2HC = CaCl + H 0 + CO Equipment - Flask, Glass splatter syringe, Bung, Marble chips (Calcium Carbonate (CaCO)) and tubing. Safety Because of the dangerous chemical that will be handled goggles should be wore during the experiment in case any should get in your eyeball while the chemical is being measured and the experiment is happening. Fair stress The amount of hydrochloric acid is the same (20ml) for for each one experiment using much(prenominal) or less of it in each one would highly tint it making the results erroneous and useless. The same amount of marble chips is used (2gs) for every experiment if the amount was too varied the results would be unusable. The test was ingeminate two times to attend fair and accurate results from averaging. Washing each apparatus that I use so that there is no nick over of acid or other substance. Plan Starting with a 0.25 molar. Fill a flaskful with 5cm 1 molar hydrochloric acid and 15cm of distilled peeing this will reduce the molar to 0.25. The Tubing should be attached to the gas syringe and the other end mystify in a bung which will be eventually be inserted in the lid of the flask (fig 1). At the last second before the bung in put on top the marble chips (2gs) should be put in to the 2.5 hydrochloric acid so to catch the full about of gas given attain and the. The temperature should be checked every 20 seconds over 200 seconds. To ensure for accurate results the test should be repeated multiple times the more times its done the more accurate the results will be. Finally you should bit by bit change the molar from 0.25 to 2 (0.25, 0.5, 0.75, 1, 2) IMAGE
