H2O temperature increases‚ then the Alka-Seltzer tablet will dissolve faster because the hot water molecules will move faster colliding with the tablet particles. Water will be the independent variable due to the fact is will always stay in its same form throughout the experiment. The Manipulated variable will also be the water‚ since I will be changing its temperature. The Responding the variable will be the timing of how fast or slow the Alka-Seltzer tablet dissolves. And the control is the glass

lab and also how many Alka-Seltzer tablets that would equate to. This was done by collecting CO2 gas by inverting a buret and submerging it under water in order to calculate the volume of CO2 released from a fragment of Alka-Seltzer tablet. The main component of Alka-Seltzer is sodium bicarbonate‚ used to neutralize excess stomach acid during illness through the following reaction that generates CO2: HCO3- + H+(aq) H2CO3(aq) CO2(g) + H2O Experimental: An Alka-Seltzer tablet was accurately weighed

Put on apron and Safety goggles. Step 2. Get Alka-Seltzer tablets and plastic film container from teacher. Step 3. Measure x ml of distilled water with the graduated cylinder and pour it into the film container. Step 4. Drop x grams of Alka-Seltzer into the film container and close lids quickly. Step 5

CO2 Lab Report Intro Alka-Seltzer tablets are used to treat cold/flu symptoms as it produces CO2 when dissolved in water. The goal of this lab is to calculate the amount of NaHCO3 is needed to produce enough CO2 gas to fill the room. Experimental One Alka-Seltzer tablet was weighed on the analytical balance. Then a piece was measured out to be between 0.21 and 0.28 grams. 500mL of distilled water was added to a 600mL beaker. 80mL of water was mixed with 20mL of 6M HCl in a 150mL beaker. A

reaction (Blauch 1). Alka-Seltzer was chosen for this experiment based on its properties which allow for a fast chemical reaction. The fizzling that occurs is the result of the chemical reaction going underway. Based on its relative ease of use and clear depiction of reaction rates‚ Alka-Seltzer was an idea choice as the substance to be tested. The chemical reaction pathway of the Alka-Seltzer as done in my

Using the glass‚ fill it with water that is 25 degrees Celsius‚ use the thermometer to make sure the temperature is correct. 2. Have my phone ready to time how long it takes for the tablet of alka-seltzer to dissolve in the water. 3. Then‚ getting another cup‚ we have room temperature water. Then‚ we drop another alka-seltzer tablet into the water and time

By crushing the Alka-Seltzer tablets to different extents‚ we were able to determine the effect of surface area on the rate of reaction. Trial 1 was the control and a full Alka-Seltzer tablet was placed in water at room temperature‚ 26.0 °C. It took 40.40 seconds for the tablet to react. Trial 4 was a crushed tablet reacted in water again at room temperature. It took 35.42 seconds for the reaction to end. Lastly‚ Trial 5 was a powder of the tablet reacted in water at room temperature

we had three flasks all containing varying temperatures of water(H20). One with cold water (4°C)‚ one room temperature (21°C)‚ and one with hot water (44°C). In each flask‚ we dropped one tablet of Alka-Seltzer‚ all within 0.008 grams of each other‚ into the three separate beakers and the duration until the tablet dissolved. The results showed a large change in the average reaction rate between the different temperatures. The cold water took 256.91 seconds to dissolve and had

investigating is the reaction that occurs when an Alka-Seltzer tablet is placed into a given amount of water. Alka-Seltzer is an over-the-counter antacid and pain relief medication that is dissolved in water before it is ingested. Each tablet contains aspirin (acetylsalicylic acid)‚ citric acid‚ and sodium bicarbonate. As the tablet dissolves in water‚ the bicarbonate ions in the tablet react with the hydrogen ions from the acids that are also contained in the tablet. The carbon dioxide gas produced by the

Then‚ an Alka Seltzer tablet was filled in the water. After a while‚ placed the flask & water & Alka Seltzer tablet on to the balance pan‚ the mass of the whole system was determined. This procedure was for the open system. For the close system‚ a flask was taking out and filled in with 15ml of water. The mass of the flask & water was determined and recorded. Then‚ an Alka Seltzer tablet was placed in a balloon‚ and put the balloon on the top of the flask‚ the Alka Seltzer tablet fell into
