Endothermic or Exothermic Reaction Lab

Problem: Will a combination of Sodium Bicarbonate( NaHCO3) and dilute Acetic Acid(HC2H3O2)
produce an endothermic or exothermic chemical reaction (or not react)?

Hypothesis: (Form your own that speaks to the problem.)
Materials:

• Erlenmeyer flask
• 250 ml beaker
• Graduated cylinder
• Triple-beam balance
• Styrofoam cup
• 80 ml Acetic Acid
• 10 grams Sodium Bicarbonate
• Timing Device (stopwatch or timer on cell phone)

Procedure:

Pour 80 ml of acetic acid in a 250 ml beaker.
Record the temperature in the beaker.
Add the Sodium Bicarbonate.
Record the temperature in the beaker at 5 Second intervals for 2 minutes.

Data: Present your data in chart and graph form.

Conclusion: Speak to your hypothesis….
