Experiment 7, Analysis of KHP by titration with NaOH Wright College, Department of Physical Science and Engineering In this experiment, you will determine the amount (percent) of potassium hydrogen phthalate (KHP) that is in an impure sample. You will determine the percent of KHP via titration using NOH with known inolarity. The reaction will follow, KHCgH00, (aq) + NaOH (aq) ---------> KNaCHO, (aq) + H20 (I) At the end point, the...

Question 4 You mass out 0.554 g of an impure sample of KHP. You use 17.25 mL of your standardized 0.0994 M NaOH to reach the end point. What percentage of KHP is in your impure sample? The MW of KHP is 204.23 g/mol. The MW of NaOH is 40.00 g/mol. Group of answer choices 63.2 % KHP 35.018 % KHP 12.4 % KHP 35.0 % KHP

Problem: A 1.523 gram sample of KHP (molar mass=204.22 g/mol) was dissolved in 20.00 mL of distilled water. Titrating this solution to the phenolphthalein end point required 15.30 mL with the NaOH solution. The balanced titration reaction is as follows: NaOH(aq) + KHC4H8O4(aq) -> KNaCgHO(aq) + H2O(1) Calculate the molarity of the NaOH solution. Show your work.

I'm determining the % Purity of KHP in an unknown sample. I have done two titrations: one with pure KHP titrated against a NaOH 0.1M solution, and the other is an unknown purity of KHP also titrated against a NaOH 0.1M solution. I am having trouble finding the percent purity of KHP, my professor said to recalculate my results because mine were too high (47.5%). Please help!!!
