Determining the Enthalpy of a Neutralization Reaction

Materials
• One pair of goggles
• One apron
• 175 mL of 1.00 mol/L HCl(aq) at room temperature
• 175 mL of 1.00 mol/L NaOH(aq) at room temperature
• One calorimeter with a stirring rod
• One 100 mL graduated cylinder
• Two 250 mL beakers
• One thermometer
• One roll of paper towel

Procedure
1. Before starting the experiment, the procedure was written and approved by the teacher.
2. An observations table was made to record the initial volume and temperature of NaOH (aq) and HCl (aq); the table also included sections to record temperatures, at 5 second intervals with a final 30 second plateau, for each of the 3 trials.
3. The locations for the waste disposal bin, the eye wash station, and the fire extinguishers were identified. …show more content…

Goggles were put on and adjusted to ensure comfort.
7. All glassware needed for the experiment was rinsed with water and dried with paper towel.
8. 175 mL of sodium hydroxide solution was retrieved and contained in a 250 mL beaker.
9. 175 mL of hydrochloric acid solution was retrieved and contained in the other 250 mL beaker.
10. 50 mL of the sodium hydroxide solution was poured into the graduated cylinder from the breaker.
11. The temperature of the sodium hydroxide solution was measured by placing a thermometer in the graduated cylinder and the measurement was recorded in the observations table.
12. The thermometer was rinsed with water and dried with paper towel.
13. The 50 mL sodium hydroxide solution was carefully poured from the graduated cylinder into the calorimeter.
14. The graduated cylinder was rinsed with water and dried with paper towel.
15. 50 mL of the hydrochloric acid solution was poured into the graduated cylinder from its beaker.
16. The temperature of the hydrochloric acid solution was measured by placing a thermometer in the graduated cylinder and the measurement was recorded on the observations table.
17. The thermometer was rinsed with water and dried with paper
