*The mass should not have changed because the mass is conserved* • Experiment Four: In a chemical change‚ the mass is conserved What you will need: Ziploc Bag filled with 20 ml of water Balance or Scale One Alka-Seltzer Tablet Procedure: 1. Find the weight of the Alka-Seltzer tablet and the weight of the Ziploc bag containing the 20ml of water. 2. Once both masses are recorded‚ add the tablet to the water and quickly close the Ziploc

The different methods of measuring acids and bases in a solution By Starsky Intro to Biology September 26‚ 2011 Lab Partners: Kristen‚ Tania and Betty Introduction When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best

1. Dancing Raisins Here’s another quick and easy science experiment. All you need is a glass of clear soda‚ such as ginger ale or club soda‚ and several small raisins. Fill a glass with soda. Leave about ½ inch (12.5 mm) of space at the top. Drop the raisins in. Those tiny bubbles attaching themselves to the raisins are carbon dioxide (CO2) bubbles. The irregular surface of the raisins enables a lot of CO2 to accumulate. When enough gas bubbles attach to the raisins‚ they act like tiny balloons

As placing a small piece of Zn(mossy zinc) metal into the test tube containing the diluted HCI(Hydrochloric Acid) solution‚ gas bubbles rose from the solution slowly at the beginning and vigorously in process of time. As this reaction continued for a long time‚ transparent solution turned into white opaque color and black precipitates were formed

06/21-06/22 Purpose: The purpose of this experiment is to examine different properties of gases in order to be able to identify them in a laboratory setting. I will be using Hydrochloric acid‚ mossy zinc‚ Bromothymol blue‚ limewater‚ Manganese‚ and Alka Seltzer‚ to test different properties of gases formed by chemical reactions. In order to extract the gas I will use several household products such as vinegar‚ baking soda‚ water‚ and hydrogen peroxide in order to create the gases to be tested.

not required to conduct the experiment‚ but it may be beneficial to do so if you can acquire the materials needed for your design. The reaction that you will be investigating is the reaction that occurs when an Alka-Seltzer tablet is placed into a given amount of water. Alka-Seltzer is an over-the-counter antacid and pain relief medication that is dissolved in water before it is ingested. Each tablet contains aspirin (acetylsalicylic acid)‚ citric acid‚ and sodium bicarbonate. As the tablet dissolves

or the cleaning sponge inside‚ here is a quick solution to solve the problem. Just fill it up with hot water and then drop a tablet or two of Alka Seltzer. The tablets will do all the dirty work for you‚ dissolving all the dirt and residue. All you have to do is flush the water out and rinse it after fifteen minutes or so. In case you don’t have Alka Seltzer lying around you can substitute this with a homemade mixture. Simply fill your vase with lukewarm water‚ add in a full tablespoon of baking soda
