Alka Seltzer Dissolve Lab Report

The temperature probe was then quickly cooled to room temperature. When this was achieved, the hot water was immediately transferred into the calorimeter. This method of keeping the temperature probe cooled before measuring a new temperature was repeated throughout the entire experiment. Temperature data was collected for 180 s while swirling the temperature inside the calorimeter. The calorimeter still contained the warm water.

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.

Observe the reaction and record how fast the Alka-Seltzer dissolves. 7. Place an Alka-Seltzer tablet into a second empty water bottle. 8. Pour 16 oz of room-temperature water into the bottle.

In our project we mixed different sizes of tablets and water and see if there is a reaction. The tablets are solids and the water is a liquid we are trying to see what happens when they collide. When Alka-Seltzer have many compounds in them. Alka-Seltzer is a medicine that is used to treat heartburn. It is made by many ingredients, which are bicarbonate, aspirin and citric acid.

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.

Mika Nijhawan 9/29- 10/10 2 MENTOS AND SODA LAB REPORT State the Problem Does the type of soda affect the size of the explosion, after mentos are added? Develop a Hypothesis If seven mentos to a 2L bottle of Diet Pepsi, then it will create the biggest geyser out of Coke, Fanta, & Root Beer because Diet Pepsi has potassium benzoate, aspartame, and the carbonation which react to mentos. Design an Experiment Materials List: 1 clear test tube 35 original flavored Mentos candies (2 1/2 rolls) 1 3x5 index card 4 2L bottles of soda (all different flavors/types) 1 2L bottle of soda water 1 100 mL graduated cylinder 1 400 mL beaker 1 pair of tweezers (preferably large) 1 small container Procedure: Stack seven mentos in the test tube When given permission take the test tube, soda bottles, index cards, and the remaining 25 mentos, to the designated area Place one of the four soda bottles on a flat area Open the soda bottle and place the 3x5 index card over it With the index card over the soda bottle, flip the test tube over and place it on the index card, so the test tube is lined with

Within the chemical reaction are two different parts, the reactant and product. The reactant, “an initial substance in a chemical reaction” was the alka-seltzer tablets, before they were placed into the water. For instance, when the untouched alka-seltzer was then placed into the water, it formed the product, “the final substance in the chemical reaction” (Tro, 2018). Now, by looking at how the water, or the solvent, dissolved the alka-seltzer tablet, it then created a solute, or a “dissolved substance” (Shuster, 2014). Another example, on a personal level, of a chemical reaction was, whenever I had a sore throat, as a child, my

Research Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌

To accurately determine this, each trial will have recorded dependent and independent variables, constants and a control. The hypothesis being researched, indicates higher temperatures allow for a rapid rate of dissolution. In this particular case with someone needing Alka Seltzer, they will feel better faster if they use hot water to dissolve the medicine before

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.

DESIGN PSOW Ajit Rajendran 13H   To Determine the Time Taken for a muffin paper cup to reach the ground, while Changing the Height of each experiment Introduction: In this experiment the aim is to determine the time taken for an empty muffin paper cup to reach the ground, by changing the height the empty cup is dropped from. Both variable mentioned are going to measured (height and time taken), when conducting the experiment. In order to have a fair experiment, certain factors will be kept the same throughout the experiment: the same paper cup will be used, the dimensions of the paper cup will be constant (where external factors do not affect the shape), the method in which the paper cup will be dropped.

This experiment has to be carried out carefully

Makes predictions, asks new testable questions and makes new hypotheses using the data A new testable question inspired by the experiment is: How does a particles hardness affect the infiltration rate? It may seem a little irrelevant, but is it possible that hardness can affect the rate of infiltration? Will a soft particle not delay the infiltration rate because it can get weathered by the water? The hypothesis for this experiment is: If a mineral is harder, then it will take longer for the water to drain because the water can’t easily travel down the funnel. Includes a potential application (How could we use your

ABSTRACT This paper scrutinises on the importance of agglutination reactions in clinical testing and diagnosis of various diseases. The ability of various antigens and antibodies to agglutinate when mixed in desired environment has been used as the basis to detect the presence of respective antigens in body. It focuses on importance of this method as it gives the results faster than various other methods and provides visible results. Diagnosis of various diseases can be done by this method provided the antibodies are present in blood, urine, plasma or fluid of bone marrow.
