For a titration experiment: I am using 1.025 M of NaOH(aq) as my titrant. My titration solution is 4.0 g of potassium hydrogen tartrate, with 300 mL of distilled water. After 4 trials, my average NaOH used was 1.680 mL. I am having problems figuring out how to calculate my findings. Each trial started with 50 mL of potassium hydrogen tartrate solution, and 2 drops of phenophthalein. Then I added 1.680 mL of NaOH (on average) to get titration to...
The data for the titration of 25.00 mL of Unknown Acid
Sample #80 with 0.1508 M NaOH (aq) was
plotted on the graph below.
To help with your analysis we have summarized some of the key
numerical values that were determined from the original data -
using the methods on Page 13 of your lab manual to graphically
determine the equivalence point.

Materials: NaOH MW = 40 g/mL, KHP - potassium hydrogen phthalate, KHC8H404, MW = 204.23 g/mol. Acetic acid, HC2H302, MW = 60.05 g/mol Part 1: Standardization of NaOH Assume 0.951 g of KHP is weighed and transferred to a 250 mL Erlenmeyer flask. Approximately 50 ml water is added to dissolve the KHP. Note that the exact volume of water is not important because you only need to know the exact number of moles of KHP that will react with...
