ChemistryWiki | RecentChanges | Preferences

You will be making bath bombs using the recipe and directions from [https://www.instructables.com/How-To-Make-Bath-Bombs/ Instructables Making bath bomb with Epsom salt and Corn starch]. However, we will only be making 1/2 a batch. 
 
Pre-lab Stoichiometry calculation 
 
The above recipe (we will be using a 1/2 batch calls for 4 dry ounces (1 dry ounce = 28.35g, equals 113g) of Baking soda to be added to 2 ounces of citric acid (57g). You will also use 2 ounces of Corn Starch (57g), 2 ounces of Epsom salt (Magnesium sulfate) (57g), 3 teaspoon oil, 2 teaspoon H2O1 and 1 drop of food coloring. If you use your balanced chemical reaction from [[2022 CP Making Carbonate Drink]] lab (write here): 
 
Balanced Chemical Reaction: 
 
 
Problems: Determine how many grams of baking soda you need to completely react all the citric acid if you start with 57g. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Question: Using your calculation and the information of the mass of Baking soda from the recipe, is the baking soda or citric acid going to be the Limiting reactant/reagent. Explain why including numbers from your above calculations and recipe.
