Our objective for the Sherlock Holmes Experiment was to illustrate that some chemicals can be identified or differentiated by simple chemical tests‚ such as solubility‚ pH‚ or color tests. In our group we had to test come common powders such as Alka-Seltzer‚ baking soda‚ flour‚ Vitamin C (ascorbic acid)‚ and salt. Other chemicals that were used to do this experiment were vinegar‚ and Iodine 2 Solution. The equipment used to do this experiment was red litmus paper‚ and 5 test tubes per group. After

the H2O temperature increases‚ then the Alka-Seltzer tablet will dissolve faster because the hot water molecules will move faster colliding with the tablet particles. Water will be the independent variable due to the fact is will always stay in its same form throughout the experiment. The Manipulated variable will also be the water‚ since I will be changing its temperature. The Responding the variable will be the timing of how fast or slow the Alka-Seltzer tablet dissolves. And the control is the

reaction (Blauch 1). Alka-Seltzer was chosen for this experiment based on its properties which allow for a fast chemical reaction. The fizzling that occurs is the result of the chemical reaction going underway. Based on its relative ease of use and clear depiction of reaction rates‚ Alka-Seltzer was an idea choice as the substance to be tested. The chemical reaction pathway of the Alka-Seltzer as done in my

lab and also how many Alka-Seltzer tablets that would equate to. This was done by collecting CO2 gas by inverting a buret and submerging it under water in order to calculate the volume of CO2 released from a fragment of Alka-Seltzer tablet. The main component of Alka-Seltzer is sodium bicarbonate‚ used to neutralize excess stomach acid during illness through the following reaction that generates CO2: HCO3- + H+(aq) H2CO3(aq) CO2(g) + H2O Experimental: An Alka-Seltzer tablet was accurately weighed

CO2 Lab Report Intro Alka-Seltzer tablets are used to treat cold/flu symptoms as it produces CO2 when dissolved in water. The goal of this lab is to calculate the amount of NaHCO3 is needed to produce enough CO2 gas to fill the room. Experimental One Alka-Seltzer tablet was weighed on the analytical balance. Then a piece was measured out to be between 0.21 and 0.28 grams. 500mL of distilled water was added to a 600mL beaker. 80mL of water was mixed with 20mL of 6M HCl in a 150mL beaker. A

Place about 10mL of distilled water into the wide mouth square bottle. Into the cap place about 1/4 to 1/3 of an Alka Seltzer tablet. 2. Place both the bottle with water and the cap containing the Alka Seltzeron the beam balance and read and record the initial total mass. 3. Remove the bottle and cap with Alka Seltzer from the beam balance. Drop the Alka Seltzer into the bottle and quickly place the cap on

Using the glass‚ fill it with water that is 25 degrees Celsius‚ use the thermometer to make sure the temperature is correct. 2. Have my phone ready to time how long it takes for the tablet of alka-seltzer to dissolve in the water. 3. Then‚ getting another cup‚ we have room temperature water.

This procedure was for the open system. For the close system‚ a flask was taking out and filled in with 15ml of water. The mass of the flask & water was determined and recorded.
