Alka Seltzer Lab Report

In a more detailed way, hydrochloric acid at room temperature is the smallest temperature in the experiment, so it should dissolve Alka Seltzer tablets within a slowest time. Likewise, the hottest hydrochloric acid sample should dissolve the tablet in a fastest way.

We placed 50 mL of vinegar, tap water, seawater into three respective beakers. 50 mL of seltzer water was placed into a jar with a lid

For our lab, we have six beakers of water. Three of the beakers contain high temperature water that range from 46 ℃ to 55 ℃, while the other three beakers contain room temperature water that range from 22 ℃ to 23 ℃. Then, we take six different colored Alka Seltzer tablets, and place them into the beakers one at a time. We record the length of time it takes for each Alka Seltzer to dissolve

How does the temperature affect the speed in which an Alka-Seltzer tablet fully dissolves in three cups filled with water with different temperatures.

Hypothesis: Altoid and Smarties will dissolve the fastest and Sweet tarts will dissolve the slowest.

I had stated in my hypotheses that: 1) If the rate at which the Alka seltzer tablet dissolves is related to the temperature, then the temperature will affect the rate at which the tablet dissolves. 2) If the rate at which the Alka Seltzer tablet dissolves is related to the surface area, then the surface area will affect the rate at which the Alka Seltzer tablet dissolves. 3) If the rate at which Alka Seltzer tablet dissolves is related to the catalyst, then the catalyst will affect the rate at which the tablet dissolves. My hypotheses were proven correct by the observations

The next step in this lab is to rinse the Erlenmeyer flask with distilled water down the drain and then repeat the experiment, this time adding 10 ml of 0.10M KI and 10 ml of distilled water to the flask instead. The flask should again be swirling to allow the solution to succumb to the same temperature as the water bath and once it has reached the same temperature, 10 ml of 3% H2O2 must then be added and a stopper must be immediately placed on the flask and recording should then begin for experiment two. After recording the times, the Erlenmeyer flask must then be rinsed again with distilled water down the drain. After rinsing the flask, the last part of the lab can now be performed. Experiment three is performed the same way, but instead, 20 ml of 0.10 ml M KI and 5 ml of distilled water will be added and after the swirling of the flask, 5 ml of 3% H2O2 will be added. After the times have been recorded, data collection should now be complete.

in the data is how it shows that larger pieces dissolve faster than smaller ones. As stated

At the T zero time interval all of the groups were found to be at about the same starting point with no real deviation between the groups that exceeded the standard error. At the 30 minute interval however, the Coke group were found to have the highest flow rate when compared to the other groups. The non-drinker and Gatorade groups were found to have about the same flow rate at the thirty minute interval while the water drinker group was found to have the lowest flow rate at the first time interval. At the sixty minute interval the drinker groups were all within range of each other while the non-drinker group had a substantial difference in flow rate and the initial steps towards a decrease in flow rate. The ninety minute interval demonstrated a spike in the flow rate for the Coke group along with an equal flow rate for the water and Gatorade group, by comparison the non-drinker group continued the downward trend although the volume levels did not drop by a dramatic amount there was still a decrease. At the end of the experiment the water group peaked in flow rate although not to the level of Coke in the ninety minute interval. Coke produced the second highest flow rate, with Gatorade behind it at the end of the

Hypothesis My hypothesis is that those who drank 16mL of water will have a higher rate of urine production than those who drank Gatorade. Similarly, those who drank regular soda will have greater specific gravity and water will have the lowest specific gravity because water dilutes the urine. On the other hand, those who drank Gatorade will have the more acidic urine than those who drank water because water has PH of 7.

Although weak electrolytes can conduct electricity, it is unable to perform as well as strong electrolytes due to the fact that it carries fewer ions. (Conductivity Theory And Practice 5-6) Based on part A of the experiment, the usage of the conductivity sensor was to measure and determine the current within the various brands of sports drink in order to record the different electrolyte levels. Additionally in part B, the technique of a pipette allowed the transport of an extra 10 additions of 1mL aliquots of the selected sport drink whilst the magnetic mixer consistently stirred the solution.The focus of this experiment, is to identify the conductivity of various brands consisting of isotonic, hypertonic and hypotonic sports drinks. Based on logic, it is predicted that Maximus will consist of the highest level of conductivity, followed by Powerade and then Gatorade due to the fact that there is an excessive level of electrolytes due to salt ions. In terms of association to the experiment, the independent variable is adjusted by the variety of sport drinks, directly influencing the dependent variable. Whilst the dependant variable aims to measure the conductivity of each

Review the four factors of dissolving you have just investigated. Given the correct solvent for a solute, what could you do to hasten the solution process?

Subjects performed an experiment to investigate the effects of fluid ingestion on kidney function, in which they measured with the kidney output. Before beginning the experiment, each subject was to take a sample collection and that was Sample 1. Once returned to class, the subjects recorded the time of urination and began to do the investigation. In order to begin the investigation, subjects drank one of the four fluids, and measured the effect it had on the urine output. The four fluids were bottled water, Gatorade, salt water, and black coffee. While preparing for the experiment, the contents of each of the solutions was investigated and written down to test what the solution could do to the balances in the body. Subjects figured out the

We both conducted the experiment each in our own test tubes to compare results. When we poured our Gatorade solution into the test tubes, we realized that we really only needed 1/16th of the Gatorade solution. After we poured the detergent into the test tubes, the solution became a dense, sticky blue goo. As we shook the solution in the test tubes, we noticed that the detergent was so thick and dense, it was difficult to mix. When the pineapple juice was added, it sunk to the very bottom of the test tubes, mixing this wasn’t as difficult as mixing the detergent, but this time, foam started form on one of them. (Humnah’s) Now, the color of the solution is blue but with a tint of green because of the pineapple juice. The last step was the alcohol, and immediately after it had been trickled down the test tube, a white layer started to appear at the top. After we let this sit for about five minutes, a white gooey layer hovered on

Have you ever took a sip of water, only to find it disgusting and hard tasting? It was probably because there was too much chlorine or the pH level wasn’t good. In my experiment, I am going to compare ten different kinds of bottled water to tap water by testing for pH, chlorine, and a few other measurements so you can find out what to drink when you’re thirsty. I am going to test the waters by dipping testing strips into the water and comparing those results to those of the tap water. My hypothesis is that the pH level of the tap water will be higher than that of the bottled water, but the chlorine in the tap water will be higher than the amount of bottled water.
