Aim – To compare the mass of the products of a 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

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

The name of the alka seltzer project is named “The Dropouts.” The significance of that name is that the owners of the machine are very close to dropping out school themselves. Ultimately‚ the goal of the machine would be to pop a balloon and to blow out a candle. The goal would be achieved by using the potential energy in the balloon‚ popping it‚ and using the now present kinetic energy‚ which is the air‚ to blow out the flame of the candle. The final products would be a popped balloon and a blown

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

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

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 to our own results. The hypothesis was that more surface area exposed and smaller volume would result in a faster chemical reaction of the material. Since the Alka-Seltzer

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 a reaction with

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

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

What factors will make an Alka-Seltzer tablet dissolve faster? My theory is that the Alka-Seltzer will dissolve faster in the warm water and slower in the cold water because the more heat something has the more energy the atoms or molecules in the object get. So in hot water the molecules inside are moving around really fast and have tons of energy to dissolve the tablet while in cold water the molecules are still moving around but at a slower pace therefore taking longer to dissolve the tablet.
