1. Give one observation that a chemical reaction occurred when the Hydrochloric acid was added to the sodium carbonate (or Potassium carbonate).
2. What did you do in the lab (look at the lab procedures) to ensure that the sodium/potassium carbonate was the limiting reactant (the reactant that ran out first) in this lab?
3. Which product did you do a Percent yield for : Chemical name ___________________________
Chemical Formula: ___________________
4. When you weighed the crucible, watch glass and the product, you assumed that all the products in the crucible was the chemical in Question 3. There are two additional products. In the space provided, please explain what you did in the lab (or what happened in the lab) to make you confident that none of that product is left in the crucible.
a. Chemical formula of the product: ______________________________________________________________________
