When I combine the H2O2 mixture with sodium bicarbonate with a light match‚ it extinguishes the fire. 3-F. When I mixed the alka seltzer tablet with the limewater it rapidly increased the volume in the well plate of the limewater mixture which means that it produces CO2 in the limewater. 4-C. I noticed no changes between the limewater and my breath through the straw.

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.

Antacids are taken to relieve heartburn or indigestion caused by excess stomach acid. For instance‚ antacids such as alka-seltzers contain baking soda which is highly reactive with acids‚ settling the discomfort of indigestion. During the lab we used vinegar and various antacids to test what was most effective and why. The brands consisted of name brand and generic‚each type
