Description

Watch the following video to see how this experiment is performed.

A. Heat Capacity of Calorimeter

Fill in the following on your report sheet:

1. Temp. of calorimeter and water before mixing: 22.0 °C

2. Temp. of warm water: 39.0 °C

3-7. (determine on your own, using the data below)

The temperature data for each 15-second interval is given in the table below. Use this to fill out the Temperature versus Time Data on page 145 for Part A. Heat Capacity of Calorimeter

Use this information to create a graph on page 146. Determine the maximum temperature of the mixture and use that value to calculate the rest of Part A (3-7.). An example calculation is given in the Discussion.

B. Heat of Neutralization of HCl-NaOH

Fill in the following on your report sheet:

1. Temp. of calorimeter and NaOH: 22.2 °C

Temp. of HCl: 22.2 °C

2-9. (determine on your own, using the data below)

The temperature data for each 15-second interval is given in the table below. Use this to fill out the Temperature versus Time Data on page 145 for Part B. Heat of Neutralization of NaOH-HCl
