198 Words1 Pages
Objectives In this lab, you will investigate the percent composition by mass of CO2 in Alka-Seltzer® tablets. In addition, you will find out how much CO2 is released into the atmosphere as 2 Alka-Seltzer® tablets chemically react in vinegar. Procedure 250-mL beaker 100-mL graduated cylinder Scale 60 mL of Vinegar 2 Alka-Seltzer® tablets Materials 1. Clean and dry 250 mL beaker. 2. Determine the mass of 2 Alka-Seltzer® tablets. 3. Measure 60 mL of vinegar using a graduated cylinder. 4. Pour the vinegar into the 250 mL beaker and measure the mass of the beaker with vinegar. 5. Calculate the mass of the beaker with vinegar plus the mass of the two Alka-Seltzer® tablets. 6. Carefully drop the two Alka-Seltzer® tablets into the vinegar

Alka-Seltzer is a medical drug that works as a pain reliever and an antacid. The pain reliever used is aspirin and the antacid used is baking soda. When sodium bicarbonate dissolves in water it splits apart into sodium and bicarbonate ions. The bicarbonates reacts with hydrogen ions from citric acid to form carbon dioxide gas and water. This is how the bubbles are made.

Alka Seltzer mixture mainly consists of 3 active ingredients; aspirin, citric acid and sodium bicarbonate. The functions of the following components are as follows; Aspirin acts a pain reliever and as an anti-inflammatory (which reduces swelling and inflammation). It does this by preventing the action of a substance known as cyclo-oxygenase which produces chemicals in the body. Sodium hydrogen carbonate and citric acid neutralizes and reduces stomach acid when they react with water.

The topic of research is, “how fast does an Alka-Seltzer tablet make gas?”. In the experiment, the scientists will be measuring the chemical reaction rates that occur, when 1 Alka-Seltzer tablet is placed in a specific temperature of water. The independent variable during the experiment will be the temperature of the water (degrees Celsius). The dependent variable during the experiment will be, the rate in which gas is produced (in seconds). The constants of the experiment, will be the amount of water used and the Alka Selter compound.

This is because varying surface areas create varying amounts of Alka-Seltzer tablet particles colliding with the water molecules from trial to trial, leading to a reaction rate affected by temperature and surface area. To fix uneven surface areas, Alka-Seltzer tablets can be crushed into a fine powder and put through a sift to create a powder of equal size. The powder can then be weighed into equal parts so the surface area and weight are controlled variables. The use of tap water allowed the alka-selter tablet to collide with more than H2O particles (such

A buffer solution minimises change in PH of a solution when small amounts of acid or alkali are added to the solution, with an an acidic buffer solutions maintaining a PH<7 (ChemGuide, 2017). It works through an equilibrium, so if the concentration of H+ or OH- are changed, equilibrium will shift to oppose this change and return solution PH to original value. The Alka Seltzer mixture contains an excess amount of the bicarbonate ion which is vital for the buffering action taking place within the solution. This is because the excess bicarbonate ion present, allows the solution to act as a buffer as it’s able to react with small quantities of acids and bases added to the solution, therefore resisting a change in PH by neutralising them.

The experiments were conducted online using Late Nite Labs. Materials: Because the experiments were conducted online there wasn’t any physical use of materials, only digital ones, for these labs to be performed. Only the registration for the website was needed to perform these online labs, as well as a desktop computer.

Citric acid, aspirin and sodium hydrogen carbonate are the main constituents of alka seltzer. Its main role is to reduce headaches, period pains, migraines, muscular pains and symptoms of colds and flues, as well has curing problems related with an upset stomach. Aspirin works to reduce pain and swellings; it is an anti- inflammatory drug and belongs to a group of drugs called NSAIDs as it does not contain steroids. The enzyme cyclo-oxygenase which speeds up the production of prostaglandins is blocked by aspirin.

This heating and cooling was repeated until there was very little (less than 0.0010 grams) fluctuation in numbers. Vial one had a start weight of 14.7681 and an end weight of 15.4098, meaning the mass of the water was 0.4658. Vial 2 had a start weight of 14.7451 and an end weight of 15.3833, meaning the mass of the water in this sample was 0.4633. The mass of the water was found by subtracting the mass of the vial with the hydrate (the start weight) from the mass after the final heating (the final weight). To then find the percent water divide the water mass by the hydrate mass and multiply by 100 since the number is a percent.

Each group was assigned a different percent of sucrose solution out of the four variables; 0% , 5%, 10%, and 15%. After we filled the beaker we then got two potato cores. Once we had the cores we cut the skin off the ends. Following this we then cut the two potato cores into four 2.00 cm potato cores. After they were cut into 2.00 cm each we found the mass.

After reflux, we removed the reaction mixture from the apparatus and cooled it for several minutes. We transferred the mixture to the beaker that contained water (30 mL). We cooled the mixture to room temperature and added sodium carbonate to neutralize the mixture. We added sodium carbonate until the pH of the mixture was 8. After neutralize, we collected benzocaine by vacuum filtration.
