Titration Data Analysis

A.  Volumetric Standardization of NaOH solution.

1. 1. Take the class data and add the following columns to the spreadsheet:

2.  Fill in each of the new columns.

3.  Calculate both an average and a standard deviation for the NaOH concentration.

B.  Volumetric Determination of KHP in Unknown

1. 1. Take the class data and add the following columns to the spreadsheet:

2.  Fill in each of the new columns, using the class average from part A for the NaOH concentration.

3.  Calculate both an average and a standard deviation for the percent KHP in the unknown.

C.  Gravimetric Standardization of NaOH solution.

1. 1. Take the class data and add the following columns to the spreadsheet:

2.  Fill in each of the new columns.

3.  Calculate both an average and a standard deviation for the NaOH concentration.

D.  Gravimetric Determination of KHP in Unknown

1. 1. Take the class data and add the following columns to the spreadsheet:

2.  Fill in each of the new columns, using the class average from part C for the NaOH concentration.

3.  Calculate both an average and a standard deviation for the percent KHP in the unknown.

E.  Statistical Analysis of Data

1. 1. We'll come back to this later after we've learned more about statistical tests.

REPORT:

Complete your notebook in LabArchives and fill out the report form. Be sure to include the spreadsheet in your notebook. In your conclusions, summarize the quantitative results, and include some qualitative comments on which type of titration you think is better, both from a procedural and a results perspective.

The completed report is due in one week.
