Acid-Base Titration Lab

Purpose

To determine the molar concentration of a base by performing a titration using an acid of known volume and concentration.

Procedure

For each acid-base system to be tested, create a data table that includes the volume of acid in the Erlenmeyer flask, the final buret reading, the initial buret reading, the volume of base used in titration in the first column.
Select the Type of Reaction (i.e. strong acid vs strong base).
Choose to fill the burette with a base.
Select the species of acid and base to be used in the lab.
Select the indicator to be used. If you are unsure which indicator to use, research the uses of both methyl orange and phenolphthalein to help you decide.
Record the molar concentration and volume of acid in the Erlenmeyer flask.
For larger amounts, use the slider to add base from the buret to the Erlenmeyer flask. As you approach the endpoint, the solution will show a brief colour change to pink that will disappear. This is the point at which you can change to adding base drop wise using the button below the slider.
Record the volume of based used to titrate the sample of acid to the endpoint.
Repeat steps # 2 - 8 using a weak acid vs. a strong base.

Communicate the results in a lab report. Including: Question, Hypothesis, Materials, Observations, Results, Discussion, Conclusion, References. Be sure to include your calculations for determining the molar concentration of both the strong and weak acids used in the titration. Also discuss any comparisons you can make between the two types of systems.
