06.05 Rate and Collision Theory: Assessment Instructions Investigation of the Rate of a Reaction Background: The reaction you will be 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

Introduction The purpose of this experiment was to determine the amount of NaHCO3 in Alka-Seltzer tables by calculating the mass of CO2 released by an Alka-Seltzer tablet when dropped into water, vinegar, and various combinations of both. Background Alka-Seltzer is an over the counter drug used to relieve cold symptoms while neutralizing stomach acid. Alka-Seltzer contains anhydrous citric acid (antacid) and sodium bicarbonate (antacid). When the table dissolves in water, NaHCO3

Sprite is a type of soda that many people drink but how can it handle an Alacelzer. It doesn’t have a color and is flavored lime and lemon created by the coca cola company. Its made of carbon water, high fructose corn syrup, citric acid, natural flavors, and sodium benzoate. To get an idea of what this is really made up of I will tell you what each ingredient is. Carbonated water is water that has carbon dioxide dissolved into it as a gas. High fructose is something sweetener that is made from corn

ALKA-SELTZER GAS STOICHIOMETRY LABORATORY REPORT. INTRODUCTION The objective of this experiment was to analyze the stoichiometry, or “the determination of the proportions in which elements or compounds react with one another”, of the gas released during the chemical reaction between an Alka-Seltzer tablet and water (Britannica n.d.). This was done first by measuring the mass of the water and Alka-Seltzer tablet separately—the reactants, the environmental factors—atmosphere and temperature, and then

After adding distilled water, alka-seltzer began bubbling extensively, as the two substances react and form CO2(g) and a buffer. Sodium bicarbonate also bubbled mildly, as it reacts with water to form carbonic acid, which then breaks into CO2(g). Aspirin, Alka-seltzer, and Tylenol showed up acidic from the Universal indicator, whereas sodium bicarbonate and the unknown were blue and basic. This is because sodium is a non-reactive ion, as it is part of NaOH, a strong base, where as bicarbonate attaches

reagents. Alka-seltzer proved to be a highly reactive reagent as bubbling occurred whenever any of the liquid reagents were mixed with it. It appears that alka-seltzer created a neutralization reaction with each of the liquids. Since alka-seltzer and baking soda contain similar chemical properties, it can also be inferred that the bubbles that were apparent for each of these neutralization reactions was the gaseous carbon dioxide that was created during the reaction. While alka-seltzer seemed to

Percent by Mass of NaHCO3 in Alka-Seltzer Tablets Introduction Determining the percent by mass of sodium bicarbonate in baking soda is important because it demonstrates the relationship between reactants and products. In this specific experiment, it demonstrates the reaction between a base and an acid. It also reveals the effect that a limiting reactant can have on the product that is produced in a reaction. Alka-Seltzer tablets aim to neutralize stomach acid and thereby reduce stomach pain, as

How much CO2? Introduction The goal of this lab was to determine the amount of grams of sodium bicarbonate (NaHCO3) required to produce enough CO2 gas to completely fill the 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

CONCLUSION: 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
