Peyton Gozon Cary Academy 2013 The purpose of this study was to determine if Alka-Seltzer would dissolve quicker depending on the amount of pieces in the liquid. Alka-Seltzers are made to dissolve quickly, in a whole tablet in water to relieve headaches, Stomach pain and heart burn. Alka-Seltzer was taken and broken apart into 2, 4, and 8 even pieces, Also there was a whole tablet being tested. The 4 pieces of Alka-Seltzer had the best time dissolving time, this is because the 4 pieces is the right size for the quickest nucleation process (The nucleation process is where co2 forms in small divots on the Alka-Seltzer, and the co2 is released), and the 2 pieces took slightly longer to dissolve, and the whole tablet took the longest, however 8 pieces took longer than the 4 pieces because the tablet is too small for the nucleation process. This is because the Nucleation process forms co2 around the tablet, dissolving the tablet, in this case reducing the pH of the liquid. However if the site for the Nucleation process is smaller, then it slows down, but if there are pieces then that is almost 2x as fast as the whole tablet. The experiment could be improved by testing the same experiments with different types of Alka-Seltzer. Also the experiments could have been taken further and tested with more types of liquids. Some experiments that could be done in the future could be: Can Alka-Seltzer affect a solids acidity ( Like steak). Also do different types of Alka-Seltzer affect how good they are at neutralizing acids.
