We will execute the reaction necessary to determine our percentages from lab 1.02 today.

Warm Up

Answer these critical questions to help you prepare for the second part of lab 1.02.

The balanced equation for this reaction is:

HCl(aq) + Na2CO3(aq) →  NaCl(aq) + H2O(l) + CO2(g)

1. Which substance must completely react; the acid or the carbonate ions?

2. How much acid do I need to use (moles, molarity & volume)?

3. What gas measurements must I collect?

4. How will I get this data?

5. Can I run multiple trials?

6. How do I find the mass of Na2CO3(s) from CO2(g)?


  • Perform a gas forming reaction and collect data to find the amount of starting compound that was consumed
  • Recall key information about periodic trends
  • Write electron configurations
