(as timer) - 2 Alka-Seltzer tablets - Electronic scale Procedure: 1. Fill the graduated cylinder with 10ml of vinegar and put it in the clean film canister. 2. Break the Alka-Seltzer tablets to two parts from the middle‚ measure both parts on the electronic scale (half tablet is 1.5g) and break little pieces from the bigger half if necessary‚ to make both parts weight as close as possible. 3. One person set the timer while the other person put half of the tablet into the film canister and close

unknown analgesic tablet using Thin Layer Chromatography (TLC) analysis. The procedure involved preparing TLC plates‚ solubilizing standard analgesics (ibuprofen‚ aspirin‚ acetaminophen‚ caffeine) and the unknown in isopropyl alcohol (IPA)‚ and developing the plates in acetone. Rf values were calculated for each compound. The unknown tablet showed an Rf value of 0.584‚ closely matching that of caffeine (0.600)‚ suggesting similar polarity. The findings indicated that the unknown tablet likely contains

Hypothesis: I believe that the more water added to the canister with the Alka-Seltzer tablet‚ the slower the reaction will be because adding more water will mean there will be more water to disperse the Alka-Seltzer (basically this will decrease the concentration of the Alka-Seltzer in water). Materials:

different temperatures of water on Alka-Seltzer tablets. In the experiment they first tested how long an Alka-Seltzer tablet would dissolve in cold water ( 9 degrees) then repeated it two more times in order to calculate a mean. Then using a hot plate to heat the water‚ they tested another tablet in the hot water (51 degrees) to see how long it would take to dissolve and again did it two more times to calculate a mean. Finally they tested another tablet in water left on the hot plate for thirty-seconds

large effervescent tablets‚ which are dissolved in a glass of water. As the tablets dissolve‚ the base (bicarbonate) and the acid (citric acid) react vigorously producing carbon dioxide gas‚ which also produces enough agitation to allow the active ingredients to dissolve slowly. o In our lab‚ our objective was to test if water at different temperatures‚ salt‚ and vinegar‚ would affect the reaction rate of Alka Seltzer tablets. However we thought‚ that the size of the tablet would not matter
