Problem:
How does the temperature of water used to dissolve an Alka-Seltzer tablet affect the amount of time it would take for the tablet to completely dissolve?
An Alka-Seltzer tablet is a medicine tablet made with baking soda used as a pain reliever for “headaches, body aches, pain, heartburn, acid indigestion, and sour stomach” (Alka-Seltzer Tablets). It is put into water, left to dissolve and then consumed. When an Alka-Seltzer tablet is dropped into h20, a chemical reaction immediately takes place and produces bubbles made out of carbon dioxide as a product of the collision (Olson 2). When in its original powder (dry) form, the Alka-Seltzer’s two main ingredients: citric acid and sodium bicarbonate are just there and not reacting to each

For example, an experiment similar to this one could be how pressure could affect the time it takes for an Alka-Seltzer tablet to dissolve. Using A flask and rubber stoppers, you can compare the amount of time it takes for and Alka-Seltzer tablet to dissolve in regular room temperature water and room temperature water in a flak but with a rubber stopper stopping the air flow into the flask. This is related to the experiment performed above because the increase in pressure from the rubber stopper stopping the air flow in and out of the flask may affect the time it would take for the Alka-Seltzer tablet to dissolve. Another example of an experiment related to the one performed above is how the amount of water used to dissolve an Alka-Seltzer tablet effects the time it takes for one to dissolve. This also relates to the experiment performed above because it also affects how fast the rate of reaction is. Like how the temperature affected how long it took for the tablet to react to the water, if there is only one drop water used to dissolve the whole tablet, the time it takes for the whole tablet to react to the water and start to dissolve will be
