How Fast Does Alka Seltzer Make Gas

The temperature probe was kept in the calorimeter until the temperature had been stabilized and was calibrated. A beaker was placed on a hot plate with dial turned between three and four. Another 100.00 ml of deionized water was added while the beaker is heating up. Using the temperature probe, the beaker was measured

Note the gradient of the line Exit the linear regression dialog and store the latest run data Add 2, 3, 4 drops of enzyme catalase solution to test tube 2, 3, 4 respectively and repeat the above procedure for each test tube. Access other groups results and fill table 4 RESULTS In this experiment it was found that increase in number of drops of enzyme suspension led to increased pressure as shown in the table 3.

Objectives In this lab, you will investigate the percent composition by mass of CO2 in Alka-Seltzer® tablets. In addition, you will find out how much CO2 is released into the atmosphere as 2 Alka-Seltzer® tablets chemically react in vinegar. Procedure 250-mL beaker 100-mL graduated cylinder Scale 60 mL of Vinegar 2 Alka-Seltzer® tablets

How is temperature related to this reaction? The higher the temperature the slower they move.

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.

Identify the independent Variable Size of the tablet Identify the dependent Variable Reaction time List the controlled variables The solution (water), temperature, volume of water (200 mls) The amount of Alka- Seltzer How will the dependent variables be measured A stop watch will be started as the pieces of Alka-Seltzer are dropped into 200ml of room temperture water Describe the expected results if the hypothesis is true The 3 smaller pieces of Alka Seltzer will dissolve quicker than the ½ tablet .

Mika Nijhawan 9/29- 10/10 2 MENTOS AND SODA LAB REPORT State the Problem Does the type of soda affect the size of the explosion, after mentos are added? 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

Developing a topic for Science Fair will never be easy unless you have a little background about that certain topic. One particular scientist is developing her topic by researching questions she has that revolved around her topic. The scientist will be researching how water temperature can affect the chemical reaction rate between baking soda and citric acid within a bath bomb. The independent variable will be the temperature of the water (mL). The dependent variable will be the chemical reaction rate which is formed by baking soda (g) and citric acid (g).

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.

When temperature is increased, the amount of obtainable energy increases; meaning that particles will move at faster pace at a higher temperature. Thus rate at which molecules diffuse will progressively speed up as the temperature increases. However if temperature of solution is decreased the rate of osmosis will decrease and rate at which molecules diffuse will be significantly less than that of higher

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

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.

Research Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌

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.
