Background info:
        When alka-seltzer or solute touches water also referred to as the solvent. There is an instant chemical reaction involving the forming of gasses. Which is in fact a sign of a chemical reaction forming. This is because citric acid mixes with bicarbonate, to form carbon dioxide bubbles.            

       Experiences I have with this would include a science inquiry I have performed previously. We tested how we can change the pressure build up of a chemical reaction by using alka-seltzer which was tested as the variable, and water. As I have learned, when changing the temperature in water the h20 molecules tend to change speed when bouncing off off each other which makes the molecules faster when bouncing off of each other. However this is the complete opposite for cold water which makes the molecules move much slower than hot or room temp water.

Hypothesis: If I change  the temperature of the solvent used to dissolve the alka- seltzer tablets then the rate of a formation of gas should change somehow.]]> 2019-02-06 19:19:37 UTC https://padlet.com/c_isabell/4k6u95tiu9xb/wish/328450127 Designing The Investigation c_isabell https://padlet.com/c_isabell/4k6u95tiu9xb/wish/329360856
  • Materials: solvent(water)which is the variable in which temperature will be changed in numerous ways, 
  • solute(alka-seltzer tablets),
  •  Stop watch to time rate of chemical reactions.

    • Procedures:
    1) Assemble whatever materials are necessary for your testing procedures. aka prepare your cup with room temp water(room temp water is my control) inside of it along with your alka-seltzer and stopwatch.
    2) Prepare alka-seltzer tablets as necessary, by simply setting them aside 
    3) Drop prepared solute into the solvent test your "control" substance. drop alka-seltzer into your cup of water 
    4) Time until reaction stops, then record time and observations. see how long the chemical reaction lasts by timing with stop watch 
    5) Repeat steps two and four for to make sure the chemical reaction is consistent
    6)Repeat steps two and four but change the control to one of the variable's which may be cold or hot water, and then do it again with the one variable you didn't test before
    7) Clean up lab station

    For observations I noticed that the movement speed of the molecules inside of the water mattered, I know this because when the hot water(faster molecule movement) was applied with the alka-seltzer. It dissolved much more fast. But, when the cold water(slower molecule movement) met with the alka-seltzer. The tablet dissolved much slower than that of the other testings. For my recordings of the tests are as show here:

The reason the rate of the chemical reaction lasted(gas formation) changed due to the warm water was because the molecules inside of the water were moving at a much faster rate than that of the regular room temp water. Therefor when the molecules of the chemicals in the alka-seltzer tablets hit the water, There may be a much faster collision of molecules. Therefor they dissolve much faster. Unlike, and opposite is the cold water. When the cold water meets the alka-seltzers chemicals which we know molecules in cold water move much slower than those of either the hot or room temp water. When the cold waters slow moving molecules collided with those molecules/chemicals of the alka-seltzer they collide slowly therefor dissolving the alka seltzer much slower. The procedures went as explained: first, we tested our variable(room temp water chemical reaction rate) then secondly. We tested what warm water could do to affect the chemical reaction rate. Lastly we tested the cold water to see how that would have affected the rate of reaction. It all went as planned and hypothesized. For mistakes or unplanned occasions (which did not happen in our experimentation's) did not affect anything. A did however find things to educate me from this experiment such as how swallowing one of these alka-seltzer tablets could cause your stomach to tear in half. Another testable question that could be made from my experiment could be how much weight could the pressure of gas formation in alka-seltzer and water launch into the air, and/or how far could it launch an object.

    Conclusion: In our experimenting specifically my hypothesis of, changing the temperature of the water would inevitably change that of the alka-seltzers chemical reaction rate, or time to dissolve. Was with no doubt proven to be 127% correct. As may be shown above or even on my graphings and recordings.]]>     2019-02-15 19:00:33 UTC https://padlet.com/c_isabell/4k6u95tiu9xb/wish/331872149
