Alka Seltzer Dissolving at Different Temperatures The variable that I will change will be the temperature of the water that the Alka Seltzer is put in. For my results I will measure the time taken for the Alka seltzer tablet to completely dissolve in water at different temperatures. Input variables: * Varying surface area of Alka-Seltzer tablet, i.e. if cut into smaller pieces or crushed it will increase the surface area. (If the surface area is increased (more powdered) the rate

Conclusion: Our group’s claim was supported because one-half of an Alka-Seltzer tablet was needed to mix with 75 ml of room temperature to cause the balloon to inflate. Using less than one gram of the Alka-Seltzer tablet did not inflate the balloon when mixed with 75 ml of room temperature water. The only trial during the first round of the experiment where the balloon inflated consists of the one-half tablet of Alka-Seltzer and the flask filled with room temperature water. Research: After making

How does the dissolve rate of the Alka-Seltzer tablets change as the temperature of the water changes? The dissolve rate is being affected by the temperature of the water. Temperature is a measure of kinetic energy in molecules (NYU). The higher the temperature, the higher the kinetic energy. Energy is required to create a reaction. Molecules with more energy come into contact with each other more often. The molecules of the reactants have to come into contact with each other, so more energy in molecules

sales on Alka Seltzer. Which the problem is Alka Seltzer Original sales went down 12% in fiscal year 2012. Alka Seltzer has put a proposal that they would like to increase the versatility of Alka Seltzer the ones who are career oriented consumers by promoting the Alka Seltzers to be used everyday. Alka Seltzer "is marketed for relief of minor aches, pain, inflammation, fever, headache, heartburn, stomachache, indigestion, hangovers, while neutralizing excess stomach acid". ( Alka Seltzer) . Alka

Title: Law of Conservation of Mass Purpose: The purpose of the Law of conservation of Mass lab is for me to attempt to verify the Law of Conservation of Mass. Procedure: Acid Base Neutralization 1. Using 2 modified, beral pipettes fill pipet an about 1/5 full of white vinegar and pipette B about 1/5 full of 1.0 M NaOh (sodium hydroxide). 2. Place the 2 Pipets on the beam balance and read and record the total mass of the 2 pipets. 3. Carefully telescope the stem of

The purpose of the lab is to study the effect of a chemical reaction, on the change in mass. Procedure: 1.Place Alka-Seltzer tablet into bottle cap. 2.Pour approximately ⅓ of bottle volume of water into the Coca-Cola bottle. 3.Using a scale, mass the bottle with water and the cap with the tablet. 4.Combine the two reactants by inserting the tablet into the bottle and by quickly screwing the bottle cap onto the bottle. 5.After the reaction occurs, mass the newly dissolved solution. 6

experiment was to mix Alka-Seltzer with Hydrochloric acid in order to analyze Sodium Bicarbonate as an active ingredient in the Alka-Seltzer. The mixture will contain hydrochloric acid to only see the composition of Sodium Bicarbonate in the tablet once it reacts. The amount that reacted allowed us to determine how much of it is present in the tablet. The amount of sodium bicarbonate will be measure by using the ideal gas law PV=nRT. The experiment will be conducted in the lab, therefore we are going

by mass of NaCO3 in Alka-Seltzer Tablets Alka-Seltzer is an effervescent antacid typically used for pain relief and neutralizing stomach acid to alleviate indigestion. Alka-Seltzer tablets contain Aspirin, Citric Acid (CH3COOH), and Sodium Bicarbonate (NaCO3). When the tablet is placed in water it undergoes an acid-base reaction and Carbon Dioxide (CO2) is a byproduct that causes the notorious “Fizz”. The objective of the lab was to measure the % of NaCO3 in an Alka-Seltzer tablet in different

The purpose of this lab was to to learn how temperature and surface area affect how fast a solute dissolves. This lab relates to what we have recently been learning in class because we have been going into deeper discussion about solutes, solvents, and the concept of solubility. In this lab, we first had to have a trial that tests whether or not the surface area of a solute affects the speed at which it dissolves in the solvent. To do this we first had everyone put on goggles for safety purposes

become a necessity for those seeking fast and easy pain relief. Several medications have been noted as beneficial and effective, and although Alka-Seltzer tablets, used for pain relief, as an antihistamine, and for nasal decongestion, has not reached the most commonly used, its effectiveness can be proven.2 Dissolved in water before ingestion, Alka-Seltzer tablets use the action of effervescence to produce the release of carbon dioxide gas.1 This release of gas allows for the fizz to occur, and for
