Titration 2 Lab

Part 1: Strong Acid / Strong Base Titration

Complete the following right after your Part 1 Graph in lab book:

• Make sure your graph is labeled and has a title.

• Write the full reaction that was taking place.

• Write the net ionic reaction.

• Open your graph from part 1 on the computer. Select analyze from the top menu then interpolate and find your equivalence point. Clearly label the equivalence point on your graph in your lab book (include values).

• Clearly label the end point on your graph (include values).

• Set up a acid/base t-chart to organize your information (be sure to include any important information you found at your equivalence point).

• Determine the concentration of the acid that you titrated using your equivalence point.

• Determine the concentration of the acid before you diluted it.

Part 2: Weak Acid / Strong Base Titration

Complete the following right after your Part 2 Graph in lab book:

• Make sure your graph is labeled and has a title.

• Write the full reaction that was taking place.

• Write the net ionic reaction.

• Open your graph from part 1 on the computer. Select analyze from the top menu then interpolate and find your equivalence point. Clearly label the equivalence point on your graph in your lab book (include values).

• Clearly label the end point on your graph (include values).

• Set up a acid/base t-chart to organize your information (be sure to include any important information you found at your equivalence point).

• Determine the concentration of the acid that you titrated using your equivalence point.

• Determine the concentration of the acid before you diluted it.

Questions about Part 1 and 2 (Complete in lab book):

• How were the graphs from Part 1 and Part 2 similar?

• How were the graphs from Part 1 and Part 2 different?

• At what pH did phth change color? What color did it start as and change to?

• At what pH did bromo blue change color? What color did it start as and change to?

When you have completed this, get the worksheet on my desk and complete it. Anything you don't finish is homework.
