Start with half and add remain half of zinc until solution lacks the blue hue. Followed by adding 10 mL of concentrated HCl. This should eliminate the zinc through gas form decant the liquid and heat until copper is dry. Weigh out the flask + copper. Then determine the percent

CHE101 Experiment date: 06/20 Write-up date: 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
