Factors that affect chemical reactions Intro: this experiment is to show us what factors affect the rate of a chemical reaction. Supplies: The Works Liquid Toilet Bowl Cleaner, TUMS antiacid tablets, a non-serrated knife, a spoon, a stirring rod, four test tubes, flame heater, a small beaker for the boiled water, rubber gloves, and safety goggles. Procedure: we filled a beaker 3/4 of the way full with tap water and brought the water to a boil. We then labeled our test tubes 1,2,3,4. We filled test tubes 1,2, and 3 half way full with toilet bowl cleaner. We then put the tubes into the test tube holder. In test tube number 4 we filled approximately 1/8 of the way full with toilet bowl cleaner and the filled it with water until it was 1/2 full. …show more content…

We took one of the quarter pieces and ground it up with a spoon. We put test tube number 3 into the boiling water, so that the toilet bowl cleaner becomes hot. Next, we put one of the quarter antacid tablets into tubes 1,3,4. We took the powdered tablet and put it into tube 3. Observations: Test tube 1: small reaction happened, it became foamy and rose around a quarter inch full with bubbles. Test tube 2:medium reaction, foam rose faster than Test tube 1- the foam reaches to the top of the tube and spilled out a little. Test tube 3: very big reaction, foam began spilling out of the Test tube almost immediately once the powdered table made contact with the toilet bowl cleaner. Test tube 4: basically nothing happened, a few bubbles were formed. 5 minutes later.... Test tube 1: sky blue colored, anti acid table didn't dissolve all the way. Foam dissipated slightly Test tube 2:sky blue colored, foam dissipated a little. All the antacid tablet was dissolved. Test tube 3: cloudy, gray-blue colored. Foam had completely settled. The whole antacid tablet was dissolved Test tube 4: very light blue, almost clear colored. No reaction happened, antacid tablet was almost completely

Problem: How does the temperature of water used to dissolve an Alka-Seltzer tablet affect the amount of time it would take for the tablet to completely dissolve? An Alka-Seltzer tablet is a medicine tablet made with baking soda used as a pain reliever for “headaches, body aches, pain, heartburn, acid indigestion, and sour stomach” (Alka-Seltzer Tablets). It is put into water, left to dissolve and then consumed. When an Alka-Seltzer tablet is dropped into h20, a chemical reaction immediately takes place and produces bubbles made out of carbon dioxide as a product of the collision (Olson 2). When in its original powder (dry) form, the Alka-Seltzer’s two main ingredients: citric acid and sodium bicarbonate are just there and not reacting to each

Our original question was what is the effect of different types of water on an Alka Seltzer tablet? What we were measuring was which type of water will make the tablet dissolve the quickest. Our hypothesis was the salt water would dissolve it the fastest, then the pond the second, and tap would take the longest. The results ended up being that the tap water would dissolve the tablet the fastest, then the pond water, and the the salt last. Our three controls are the amount of salt, the amount of water, and the size of the tablet.

Introduction Alka-Seltzer has been on the market since 1931 and has helped to relieve indigestion and upset stomach. The tablets began to fizz and bubble when dropped into water. “The fizziness happens when baking soda (sodium bicarbonate) and citric acid react chemically in water. They yield sodium citrate, water and carbon dioxide gas, which causes bubbles.” Based on this information, we will measure the reaction time of AlKa- Seltzer dissolved in 200 ml of water at 3 different tempertures in the first portion of this experiment.

However, after refluxing for a while, yellow precipitates begin to form near the top of the flask. It was assumed that the remaining starting material was concentrated from a decrease volume to reappeared in solution. Nevertheless, this may have been a sign of contamination that will negatively affect the entire reaction. This observation later resulted in a yellowish

If I had a chance to do this experiment once again. I would improve this experiment by actually testing, whether temperature affects the rate of reaction of the alka seltzer tablet, by having the water be hot, warm and cold, and determine at which temperate does the tablet dissolve faster. I could also change the amount of water I used during the experiment, as I only used 100ml of water in a 400ml beaker. I would also change the temperate of the room. A further investigation can study how temperature affects the rate of reaction between water and alka seltzer tablets.

The first step was to buy a 2L bottle. After that, all of the liquid inside of the bottle had to be emptied, and the plastic labels on the outside, if any, had to be removed. Then, the bottle had to be filled to the very top with water. After completing this, the Plastic Pipet had to have the metal nut attached to it, and the Pipet had to be filled almost to the top with water. Then, an empty glass or cup had to be completely filled with water, and the Pipet had to be placed in it.

The Problem: How does temperature affect the dissolving time of an antacid tablet? Antacid tablets are medicines that help neutralize the acid in your stomach. Antacid tablets are made of numerous numbers of components, such as sodium bicarbonate (baking powder), magnesium hydroxide, critic acid, and many others. When Antacid tablets are placed in water, they undergo a chemical reaction, where the sodium bicarbonate breaks apart to make sodium and bicarbonate ions. When the bicarbonate ions collide with hydrogen ions, it produces carbonic acid.

Tube 1 had 1 drop, tube 2 had 2, and each tube after had an additional drop until tube 5. Next, deionized water was placed in each tube. Tube one had 4 drops; tube 2 had 3 drops and the pattern continued until tube 5. After each tube was filled with the glucose and deionized water, the contents were mixed and centrifuged. After the tubes were centrifuged, any pellets formed during the process were removed.
