What is the Percent by Mass of NaHCO3 in Alka-Seltzer Tablets? Introduction: The moment an Alka-Seltzer tablet hits water, it begins to fizz. These tablets are over-the-counter antacids and pain relief medications that contain aspirin, sodium bicarbonate, and citric acid. The fizzing is a result of a reaction occurring where carbon dioxide (in the form of bubbles), water, and sodium acetate is formed. The fizzing and carbon dioxide bubbles are a result of the sodium bicarbonate splitting and reacting

Alka-seltzer Lab Report Statement of the Problem: The question of this lab was to find the optimum amount of Alka-Seltzer and water to achieve the highest launch possible. As Alka-Seltzer can dissolve in H2O and release CO2g (carbon dioxide gas), the gas is trapped inside the container and starts to gain pressure. This is the combination produces Sodium Bicarbonate which releases CO2g and other products. When the pressure in the container reaches maximum pressure, the lid will pop off releasing

question for the Alka Seltzer Lab is, “What is the effect of different surface areas of an Alka Seltzer tablets reaction time?’. Inside of an Alka Seltzer tablet there are two key ingredients; which are citric acid and baking soda. When a tablet is dropped into a liquid, the acid and baking soda show a physical reaction of fizzing and eventually dissolving. Materials needed for this lab was goggles, aprons, beakers, water of the same temperature, mortar pestle, and three alka seltzer tablets. In each

Introduction: The purpose of this lab is to see how fast an Alka-Seltzer tablet dissolves in water when the surface area increases. Problem Statement: How does surface area influence the Alka-Seltzer tablet on how fast it can dissolve in water? Hypothesis: If the surface area increases then the time it takes to dissolve will decrease. Investigation Diagram (ID) Title: The effect of surface area on how fast an Alka-Seltzer tablet dissolve in water Hypothesis: If the surface area increases then the

Alka Seltzer is a medical drug used for pain relief and used for relieving indigestion. For example, if you have a stomachache or some indigestion problems, Alka Seltzer may help neutralize the stomach acidity. Not only that, Alka Seltzer is also used for cleaning household items, such as vases or jewelry. Alka Seltzer contains citric acid and sodium bicarbonate, which makes it dissolve and release carbon dioxide gas when dropped in water. In this experiment, my lab partner, Rebecca, and I are trying

In this lab we tested how changing the content of the water affects the speed of the alka seltzer dissolving. My hypothesis was that the tap water would dissolve the tablet fastest, the salt water would be second fastest, and the sugar water would be the slowest. I was correct that the tap water would dissolve the fastest, but I was wrong in that the salt water would dissolve faster than the sugar water. I think that our results came out the way they did because of the amount of sugar and salt we

The Percent by Mass of NaHCO3 in Alka-Seltzer Tablets Introduction Alka-Seltzer tablets are advertised to provide one relief from headaches, indigestion, heartburn, and upset stomachs.1 When mixed with water, a bubbling action took place. The components of each table include 325g of aspirin (acetyl salicylic acid, C8H12O4), 1000 mg of citric acid (C6H8O7, 1916 mg of sodium bicarbonate (NaHCO3), and other inactive ingredients.1 The aspirin is responsible for pain relief. Citric acid and sodium bicarbonate

Joy Morounfolu Lab Partner: Ruth Bochung Chem-C 103 Section 1455 10 October 2017 What Is the Percent by Mass of NaHCO3 in Alka-Seltzer® Tablets? Introduction Ever wonder about the chemical makeup of tablets that people take for pain relief? Before a tablet can be successfully made, the limiting and excess reactants must be considered. The limiting reactant will affect the amount of the product that can be made. Another reason why the starting reactants must be determined carefully is to make reduce

he experimental variable in this experiment was the changing number of Alka Seltzer tablets that were put into the 250mL beaker of vinegar. Some of the control variables in this experiment were that the same beaker and thermometer were used for each trial, the same type of vinegar and Alka Seltzer were used for each trial, and the same amount of vinegar. The original Hypothesis was that more Alka Seltzer would increase the temperature of the vinegar was not correct. After analyzing the data it
