Alka Seltzer and water experiment

Introduction to Experiment. Alright, to begin, here are the important aspects of our experiment, testing the chemical reaction between Alka-Seltzer and water This reaction rate experiment explores the affects of surface area, temperature, and pressure on the rate of a chemical reaction. In this experiment, the reaction is between an Alka seltzer tablet (sodium bicarbonate + citric acid) and water. When an Alka seltzer tablet is placed in water, the H+ ions from citric acid react with the bicarbonate. Step 5. Make a small paper cone and tape it to the top of the rocket if you would like a nose cone. Step 6. Hold the rocket upside down and add water to the canister to one-quarter full. Step 7.

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.

Alka Seltzer Experiment by Emilie Bernier - Prez

The purpose of this experiment was the reaction rate, and how surface area affected the reaction rate between water and alka seltzer tablets. The half crushed tablet had more particles in the tablet causing more surface area to dissolve in the water. The more surface area in the tablet, the more efficient it is in reacting in with water Oil is also less dense than water, so the water sinks to the bottom and the oil ends up on top. *It's important to use water-based paint for this experiment. Not that any paint for kids is oil-based, but just saying! When you drop an Alka Seltzer into your lava lamp, it won't react with the oil
