Data: Table 2 for the most parts was simply weighing the products, this was the case for the categories as follows: mass of beaker and liquid, Mass of Alka-Seltzer, and mass of contents in the beaker after the reactions completed. The two sections in this table that required math was total mass of content in the beaker before reactions and mass of CO2 produced. To find the total mass of contents in the beaker before the reaction began we added the Mass of the beaker and liquid plus the mass of the Alka-Seltzer tablet. Sample can be seen of this below in the Data section. To find the mass of CO2 produced we took the total mass of the contents in the beaker before reactions minus the mass of the contents in the beaker after the reaction. …show more content…
This lab also showed us what is the limiting reaction along with how to find the mass of NaHCO3.
Materials: 8 Alka-Seltzers tablets, 200 mL white vinegar, (3) 250 mL beakers, (2) 50 mL graduated Cylinders, Distilled …show more content…
We also, while setting up for the individual experiments noted the temperature of the room, and the atmospheric pressure given by our instructor, this information can be found at the top of Table 2. Then we started on the individual experiments by pouring the recommended amount of distilled water and vinegar into each beaker per the table below. Once the liquid was in the beaker we weighted the beaker and the liquid inside as a mass. After measuring the beaker and the vinegar/water mixture we took the mass of the Alka-Seltzer tablet alone, then placed into the beaker and waited for the bubbling to stop before weighing the total mixture again. This was done a total of 8 times once for each experiment mix laid out below in table 1. During this time experiment 2 was spilled by mistake and so we had to redo the entire experiment over again and not try to continue with the spilled

Alka Seltzer Lab Report

Chemical reactions occur when reactants come in contact with each other. This lab observed the chemical reaction between two Alka-Seltzer tablets and water. Alka-Seltzer tablets are used to treat aches in the body, acid refluxes and stomach ingestions. Alka-Seltzer tablets contain crystals of sodium bicarbonate and citric acid. These crystals do not interact with each other in their dry states, however, when an Alka-Seltzer tablet is dropped in water a…

Alka Seltzer Lab Report

Alka Seltzer is common antacid taken to alleviate an upset stomach. It is a combination of sodium bicarbonate, citric acid, and calcium hydrogen phosphate. These substances produce a medicine that can neutralize stomach acid. Alka Seltzer is known to fizz, a reaction that is produced when carbon dioxide gas is released when the tablet is dissolved. The purpose of this lab was to determine the mass of sodium bicarbonate, Na3HCO3, in a tablet of Alka Seltzer by massing and dissolving fragments of the…

Alka Seltzer Lab Report

what a relief it is!” Alka Seltzer, a common reliever of minor heartburn and indigestion pains, comes in the form of a tablet and contains anhydrous citric acid and sodium bicarbonate. When Alka-Seltzer tablets are dissolved in water, bicarbonate forms from the sodium bicarbonate. In turn, this reacts with hydrogen from the citric acid to form water and carbon dioxide gas. In this experiment, my group determined the most effective and speediest way to dissolve an Alka Seltzer tablet. There were…

Alka Seltzer Dissolve Lab Report

The hypothesis stated above (If the temperature of H2O used to dissolve an Alka-Seltzer tablet increases, then the amount of time it takes for the tablet to completely dissolve will decrease) has proven to be true because of the data collected from the experiment performed. The data collected proved that as the temperature of the water increased, the rate at which the Alka-Seltzer dissolved increased making the time it took for one whole tablet to dissolve to decrease. For example, in the data table…

Alka Seltzer Lab Results

In this experiment, I will test the effect of temperature on reaction time for Alka-Seltzer dissolving tablets. Experiment one uses room temperature water, experiment two, hot water, and experiment three, ice water. In order to determine the effect of the water temperature, I will need to record the time it takes for the Alka-Seltzer to dissolve completely. Room Temperature Water: Fill a clear glass with exactly 8 oz. of room temperature Use a thermometer to read and document the temperature of the…

Alka Seltzer Concentration Lab Report

The goal of this experiment was to determine how much % of NaHCO3 was in the Alka Seltzer tablets by exploring the relationship between the amount of reactant and product. In order to answer the following question, vinegar, water, and alka seltzer were used as the reactants. After mixing these reactants together, water, carbon dioxide, and sodium acetate were produced. When more vinegar was added, the percent by mass of NaHCO3 kept increasing and then it reached a steady value. When the more volume…

Lab 2 Some Factors Affect Reaction Rate Essay

the temperature of the water was 35°F it took 120 seconds for the Alka Seltzer tablet to dissolve. While, when the temperature increased to 81°F the reaction took only 33 seconds, and it took only 18 seconds for the tablet to fully dissolve in 150°F water. In second case, the more surface contact between the reactants, the higher the rate of reaction. The less surface contact, the lower the rate of reaction. When chunks of Alka Seltzer were placed in the water, the surface contact increased, and it…

Ice-Cold Water Temperature Lab Report

To start off the experiment, the group collected the materials as listed above prior to the start of the experiment. Safety precautions that should be noted before the beginning of this lab are, no covering the container in which the reaction is about to take place, and it is recommended to keep the temperature of the water between 5-85°C. With the beginning of the experiment, three 250 mL beakers were taken each to hold different temperatures of water. Taking the first beaker, water was taken from…

Essay on Lab: Chemical Reaction and Aluminum Foil

Purpose: This lab experiment is divided into two parts. The first part illustrates the effect of concentration on the rate of reaction. The second part depicts the effect of temperature on the reaction rate. The first experiment will be conducted with procedures already given; this experiment will examine the effect of concentration of distilled water to the rate of reaction of NaOH and HCl solutions and aluminum foil. Meanwhile, the second experiment will require the creation of procedures involving…

Research Paper On Atoms

For example, gold is an element and is made of gold atoms. Atoms are the basic building blocks of matter that make up everyday objects. A desk, the air, even you are made up of atoms! There are 90 naturally occurring kinds of atoms. Scientists in labs have been able to make about 25 more. Protons- carry a positive charge -1 amu= heavy In 1968 new particles were discovered inside the proton called quarks. There are 3 quarks in each proton and gluons hold them together Neutrons carry no charge-…
