In the Titration Lab, how would it affect your results if you used a beaker with residual water in it to measure out your standardized sodium hydroxide solution?
Homework Answers
If you take a beaker with some residual water, the titration of standardized sodium hydroxide solution with an acid will give end point later or you will get a positive bias. This is beacuse, the NaOH is now diluted by some factor because of the residual water and hence the volume required to titrate will be more than the actual amount (without residual water).

In this experiment, you will identify an unknown weak acid by titration with standardized base. This lab takes place in two parts, which you can do in either order: 1. Standardization of a sodium hydroxide solution to find its actual concentration (approximately 0.1 M) 2. Titration of the weak acid with the sodium hydroxide solution. You won't know if your acid is monoprotic (HA), diprotic (H2A), or triprotic (H3A). a.) Indicate how you would differentiate between the three different types...
