I have to complete a lab report for a class using data collected and I have no idea how to use this data. Please help!
Homework Answers
The values are read in the graph:
Volume at equivalence point: 15 mL
Midpoint volume: 7.5 mL
pH 1/2 = pKa = 4.33
Ka = 10 ^ -4.33 = 4.7x10 ^ -5
If you liked the answer, please rate it in a positive way, you would help me a lot, thank you.
