Rinse and flush a burette with the solution of NaOH provided and set it up. Fill the burette with the solution of NaOH solution.
Using a 15-mL volumetric pipette, collect an accurate volume of the 0.1 M HC1 solution and add it to a 250-mL beaker that contains about 50-mL of deionized water and a magnetic stir bar. Place the beaker on a stir plate and begin stirring.
Turn on the Vernier LabQuest by pressing the silver power button in the upper left corner. Connect a pH probe into the slot marked CH 1, this slot is located on the top edge of the LabQuest. The LabQuest will automatically recognize the type of probe and begin to display the pH data.
Using the stylus provided tap the tabs displayed at the top of the screen to toggle between the Meter screen, Graph screen and Data Table screen.
Conduct the titration by adding the basic solution from the burette to the acid solution. You should take the pH reading after every addition of I.00 mL of the base solution. Continue the titration process until you have added 30.00 mL of the base solution.
Rinse the probe several times with tap water followed with deionized water.
Insert the clean probe you just rinsed in the acid solution labelled X and determine its pH.
Insert the clean probe you just rinsed in the base solution labelled Y and determine its pH.
Dispose the waste according in the labeled waste disposal container.

GRAPH GUIDELINES
Submit a FULL PAGE OF titration curve by stapling it to this report sheet. Your graph will be graded based on the âChemistry Graph Checklistâ posted on Blackboard, which includes overall appearance. You may seek out help from peers while learning to use Excel, but your graph must be your own.
1. Appropriate tittle (5 points)
2. Correct labelling of both axes (10 points)
3. Correct units on both axes (10 points)
4. Graph occupying at least ¾ of the page used (5 points)
5. Correct scales for both axes (10 points)
6. General shape of the graph (10 points)
Please someone helps me I did it but i dont know what im missing
As for the maleic acid solution, about 25 mL of maleic acid solution was acquired. This acid solution is ready for titrationby dispensing 10.00 mL of it(via pipette) into a 150 mL beaker. About 50 mL of deionized water was added to it. A pH probe is rinsed off and placed into this solution.
For the titration itself, a burette is used to add NaOH solution to an maleic acid solution a little at a time. The volume added below is the NaOH
1. Determine the pKa(s) and the Ka(s) of the acid worked with. This will require you to determine yourtitrationâs equivalence and half-equivalence point(s), including the solution pH these were reached at.
2. The actual pKa1 and pKa2 values of Maleic acid are 1.83 and 6.07 respectively. Calculate the percent difference between these numbers and the pKa1 and pKa2 values you determined from your data. To do this, subtract the smaller number from the larger and divide by the provided/literature values.
