How Fast Does Alka Seltzer Make Gas

621 Words3 Pages

The topic of research is, “how fast does an Alka-Seltzer tablet make gas?”. In the experiment, the scientists will be measuring the chemical reaction rates that occur, when 1 Alka-Seltzer tablet is placed in a specific temperature of water. The independent variable during the experiment will be the temperature of the water (degrees Celsius). The dependent variable during the experiment will be, the rate in which gas is produced (in seconds). The constants of the experiment, will be the amount of water used and the Alka Selter compound. The control in the experiment is water. Units used while timing the productivity of gas from an Alka-Seltzer tablet in different temperatures is, seconds. In order to find out if temperature controls the rate of chemical reaction, whether hot water is a more effective way to make the gas produce at a faster speed, it would be necessary to compare the results of different temperatures at the end of each trial. In order to do this the scientists will measure the volume of gas that is produced within a 10 second interval time after the tablet begins to react. Then the scientist will observe the different rates of reaction with temperature. The Boltzmann distribution of law, indicates that high temperature makes molecules gain high energy contents (pubs.acs.org/doi/abs/10.1021/ja). In order to measure the reaction rate, the scientists must use the same volume of water at three different starting temperatures: hot tap …show more content…

To accurately determine this, each trial will have recorded dependent and independent variables, constants and a control. The hypothesis being researched, indicates higher temperatures allow for a rapid rate of dissolution. In this particular case with someone needing Alka Seltzer, they will feel better faster if they use hot water to dissolve the medicine before

    During one experiment the results were, they found out that the higher the temperature of the water the faster the molecules will move and the lower the temperature the slower the molecules move. The molecules are what are make the alka-seltzer dissolve. So if they move slower the alka-seltzer dissolves slower, same as if the molecules move faster than the alka-seltzer will dissolve faster. Also according to a state science fair the results were that it took 19.53 seconds for the alka-seltzer to dissolve in hot water, 36.15 seconds for the alka-seltzer to dissolve in the warm water, and 96.17 seconds (1 minute and 36.17 seconds) for the alka-seltzer to dissolve in cold water. The alka-seltzer dropped in the cold water proved to dissolve the

    Introduction: In this assignment, I will be doing two experimentations on examining the impact of temperature on the Alka-Seltzer’s response time. The first experimentation that I will be doing involves some water that is room temperature. The second experimentation that I will be doing involves some water that is very hot. If I want to be able to figure out the impact of the temperature on water, I will have to document the time it will take for the Alka-Seltzer to go into solution.

    Alka-Seltzer is something that when it gets put into water it has a chemical reaction because it starts to bubble up and when it starts to bubble up the bubbles are carbon dioxide gas. Chemical reactions start when matter is mixed with other matter, you can recognize new compounds by their color or by their acid levels or how a compound looks, feels, or how it acts. Substances create a solid compound. The chemical reaction also happens from more products and properties. They can have one or more products or properties.

    In this particular experiment the constant condition, the factor that was never changed, was the room temperature water. The independent variable, the variable the student affected, was how much water was placed into the beakers. The dependent variable, a variable that was affected by the independent variable, was the time it took for the tablet to fully dissolve. The control group, which did not receive treatment from the students, was the 50 ml of water as a result of being the medium between the three measurements of water. Finally, the experimental group, the subject that was exposed to the variable during the experiment, was the 25 ml and 75 ml of

    Repeat steps 1-10 for two more trials. Conclusion: 1. I chose to compare temperature and amount of reactants in my experiments. I chose these because I thought they would reveal the the most drastic time differences. I also chose these factors because I had prior knowledge of them before I even started chemistry.

Develop a Hypothesis If seven mentos to a 2L bottle of Diet Pepsi, then it will create the biggest geyser out of Coke, Fanta, & Root Beer because Diet Pepsi has potassium benzoate, aspartame, and the carbonation which react to mentos. Design an Experiment Materials List: 1 clear test tube 35 original flavored Mentos candies (2 1/2 rolls) 1 3x5 index card 4 2L bottles of soda (all different flavors/types) 1 2L bottle of soda water 1 100 mL graduated cylinder 1 400 mL beaker 1 pair of tweezers (preferably large) 1 small container Procedure: Stack seven mentos in the test tube When given permission take the test tube, soda bottles, index cards, and the remaining 25 mentos, to the designated area Place one of the four soda bottles on a flat area Open the soda bottle and place the 3x5 index card over it With the index card over the soda bottle, flip the test tube over and place it on the index card, so the test tube is lined with

  • Four Drinking Categories Lab Report

    The methods used in this lab experiment consisted of having four different drinking categories. These categories were non-drinkers, Coke, Gatorade, and water; the subjects will be chosen randomly to drink one of the drinks and then void 30 minutes after. After voiding, the subjects will have measured their urine temperature, urine volume, calculate specific density, urine pH and urine flow rate. After the calculations are done, the subjects will use the Labstix strips to measure if their urine tests positive or negative for blood, ketones, glucose, and protein. In my hypothesis I will expect water to have the greatest urine volume and flow rate, then all other drinks (Gatorade, Coke, and non-drinkers).

    In the blue dye experiment the dye in the hot water moved faster than the dye in the cold water because molecules move faster when heated than molecules in cold water. In the hot beaker the water molecules attracted each other faster because molecules move faster in hot water. In the cold beaker the water molecules attracted each other but molecules move slower in cold water. The pattern of the cold water was stringy because the molecules move slower so the dye spread out slower. The pattern in the hot beaker spread out pretty fast but the dye did not go to the bottom of the beaker because heat rises.
