1. Alka-Seltzer Lab (Plopp, Plopp. Fizz, Fizz.)

2. The purpose of this lab is to discover what the ideal conditions would be to dissolve an alka-seltzer tablet as fast as possible.

3. If water is warmer, and an alka-seltzer tablet is placed in it, then it will dissolve faster than it would if it was placed water with a lower temperature.

4. IDV: The independent variable is the temperature. We changed the temperature of the water the alka-seltzer was placed in to test the hypothesis.

     DV: The dependent variable was the time. We collected how fast the tablet dissolved in minutes/seconds.

Conclusion:

        The purpose of this lab was to test what the ideal conditions are in which to dissolve an alka-seltzer tablet. The hypothesis was that if water is warmer, and an alka-seltzer tabled is placed in the water, that the tablet would dissolve faster than it would in colder water. When a tablet was dropped into warm water, it dissolved within seconds, compared to an approximate minute with the room temperature water, and almost two minutes in the colder water. The reason for this is that the warmer water had faster moving particles, which are able to surround ...
