Stoichiometry Loss of CO2

• Purpose

• To apply the concept of limiting reactant to
  determine the stoichiometry of a reaction using
  the method of continuous variation.

• Safety Considerations

• You will be using 3 M H2SO4 (sulfuric acid) in
  this experiment. This can cause severe chemical
  burns to your skin and burn holes in your
  clothes. Wipe up any spilled H2SO4 immediately
  with wet paper towels.
• All reagents used in this experiment can be
  safely poured down the drain. Flush with plenty
  of water.

Stoichiometry Loss of CO2

• Procedure

• Your instructor will assign you a set of trials
  to perform.
• For each trial, weigh the appropriate amount of
  Na2CO3 into a pre-weighed, clean, dry flask.
• Measure out approximately 2.68 g of H2SO4 in a
  small, dry beaker.
