After observing how Alka-Seltzer reacted in room temperature D.I. water, a variety of different hypothesis could be made as to how the Alka-Seltzer would react when the parameters were changed. Three of these include: 1) How the Alka-Seltzer would react when the temperature of the water is increased, 2) when the temperature of the water is decreased, and 3) how it would react when placed in a completely different medium, Isopropyl Alcohol. The predictions were that the Alka-Seltzer Tablet would dissolve faster than the contro

From the data table the following information can be obtained. The rate at which the Alka-Seltzer dissolved in room temperature D.I. water ranged from 31.46 to 51.46 grams/ sec., with a mean of 39.97. For the hypothesis #1 (how the tablet would react in hot water), the tablet dissolved in 24.71 grams/ sec. For hypothesis #2 (how the tablet would react in cold water), the tablet dissolved in 60.45 grams/ sec., 60.17 grams/ sec. and 44.91 grams/ sec. For hypothesis #3 (how the tablet dissolved in Isopropyl alcohol) the tablet dissolved in 701.63 grams/ sec.

l in the hot water, slower in cold water and extremely fast in the alcohol.
