Alka-Seltzer Reaction Rates Lab What are the different factors the effect the reaction rate of Alka-Seltzer? Matthew Arkfeld Leah Gilligan Jessie Abbott Period 4 June 2nd‚ 2008 Background Research: o The objective of the experiment was to determine if different factors affect the reaction rate of Alka-Seltzer. Alka-Seltzer provides fast relief to acid indigestion‚ upset stomach‚ heartburn‚ headaches‚ body aches and pains. It is an antacid and pain relief medicine used by millions

chemical reaction with the mass of its reactants. Hypothesis- The total mass should increase Materials – 1x Safety glasses. 250ml conical flask. 4x Alka-Seltzer tablets. 1x Balloon. Matches. 1x Electronic balance. 100ml measuring cylinder. Water. Method – *Place the conical flask on the balance and pour in 100ml of water. 1. Place two tablets alongside the conical flask and record the total mass. *Remove the flask from the balance and drop the tablets into the water. 2. When the reaction is complete

Alka-Seltzer Experiment Ideas 1.) Put Alka-Seltzer in different liquids and observe the reactions. 2.) Put Alka-Seltzer in different sealed containers (film canisters‚ sandwich bags‚ etc. and observe the reactions. 3.) Explore activity using Pop Rocks candy. 4.) Put Alka-Seltzer tablets into four different liquids (milk‚ orange juice‚ Coke‚ water) observe the reactions. 5.) Place Alka-Seltzer on a plate and pour a steady stream of water on it to see if it reacts any differently than

During this lab we tested the reaction of alka seltzer in water. We used water and bromothymol blue (BTB) to help hypothesize what was happening with the alka seltzer in water. When we put the alka seltzer tablet in the water‚ it started fizzing. It created a lot of bubbles in the water which tells us that some kind of a gas was created when the alka seltzer was put into the water. The next step was the hypothesize what that gas might be. That mystery gas created by the alka seltzer in water had

Amount of Water Colin Lee Dr.Cooper Chemistry 12 Introduction: Alka-seltzer contains three active ingredients‚ aspirin‚ sodium hydrogen carbonate and citric acid. It is used for headaches‚ migraines‚ and cold and flu symptoms. Alka-Seltzer is usually taken when dissolved in a glass of water. When placed in water a series of chemical reactions result into Sodium citrate and Sodium acetylsalicylate. The sodium citrate would act as the antacid for stomach pains‚ and the sodium acetylsalicylate

Determination of NaHCO3 in Alka-Seltzer Introduction: Sodium Bicarbonate also referred to as baking soda‚ Bicarbonate of soda‚ Sodium hydrogen carbonate‚ and Carbonic Acid Monosodium salt‚ acts an ionic or salt compound when put in an aqueous solution. Its molecular weight is 84.006 g/mol and it is usually found in a dry powder form that is similar to slat. It is white‚ odorless‚ and has a melting point of 108.9 degrees Celsius. It has a density of 2.1 g/cm3. Sodium Bicarbonate is an electrolyte

When researching similar projects the scientists found a project where they tested the effect of three different temperatures of water on Alka-Seltzer tablets. In the experiment they first tested how long an Alka-Seltzer tablet would dissolve in cold water ( 9 degrees) then repeated it two more times in order to calculate a mean. Then using a hot plate to heat the water‚ they tested another tablet in the hot water (51 degrees) to see how long it would take to dissolve and again did it two more times

Alka-Seltzer Form Purpose: The purpose of this experiment was to determine if changing the form of Alka-Seltzer when added to the water‚ affects the time it takes for the cap to burst. Introduction: Alka-Seltzer is a remedy for indigestion that is dissolved in water and ingested by mouth. The active ingredient is sodium bicarbonate‚ which is baking soda. Alka-Seltzer reacts with water to produce carbon dioxide gas. In an enclosed space‚ like a film canister‚ the pressure of the gas increases

experiment looked if the surface area to volume ratio affected the speed of a chemical reaction. For this experiment‚ a film container was filled one-half full with water. Then an Alka-Seltzer tablet was added‚ quickly covered with a cap and was observed until the film cap popped off. The time was then immediately recorded and the procedure was the repeated three times each with whole and crushed Alka-Seltzer tablets. Then results from three fellow classmates’ experiments would be recorded and added

the ‘Rates of Reactions’ lab is to learn how to plan an investigative lab without outside help and to learn about the ‘Rates of Reactions’. This lab will require students to take responsibility for their own learning and use their prior knowledge to aid in the completion of this lab. In the lab prepared below‚ students will be learning about Rates of Reaction with varying concentrations of Alka-Seltzer with water. Hypothesis: I believe that the more water added to the canister with the Alka-Seltzer
