Alka Seltzer and Water Chemical Reaction - Video & Lesson

With this particular experiment, we worked with Alka Seltzer, which is a base, or a molecule that can take up hydrogen ions. This is in contrast with an acid , which is a molecule that donates. The Alka-Seltzer Experiment; Published on Mar 28, 2020. Abstract. The objective: The purpose of this experiment was to find out whether there was an optimum amount of Alka-Seltzer to water that would pop the lid of the film canister that they were contained in. My hypothesis on this was that 1/2 of an Alka-Seltzer and 1/3 of a canister of water. Alka-Seltzer is a medical drug that works as a pain reliever and an antacid (antacids help neutralize stomach acidity, such as heartburn). The pain reliever used is aspirin and the antacid used is baking soda (sodium bicarbonate, NaHCO 3).To take the tablets, they should be fully dissolved in a glass of water

Reaction Rate Experiment with Alka Seltzer Tablets

Why this Science Experiment Works. The water and oil do not mix and the oil doesn't change color because the food coloring is water soluble. The Alka Seltzer reacts with the water to make bubbles of carbon dioxide. The bubbles attach themselves to the blobs of colored water and bring them to the top of the glass In this experiment, you will be measuring the time it takes for one Alka-Seltzer tablet to react completely in water. You will investigate how the reaction time changes as you vary the particle size of the reactants. You will use the same glass for repeated trials, so it is convenient to mark the desired water level Cut out a pie shape from the circle and twist the paper into a cone. Tape the cone together then tape it on the open end of the paper tube. Turn the rocket upside down and fill the canister 1/3 full with water.
