In what molar ratio do the titrant and KHP react 

### Experiment: Titration of KHP with NaOH #### Overview This experiment involves the titration of potassium hydrogen phthalate (KHP) using a sodium hydroxide (NaOH) solution. #### Data Collected **KHP Measurements and Trials:** 1. **KHP 1 (Trial 1):** - Mass of KHP: 0.3130 g - Final Buret Reading: 16.72 mL 2. **KHP 2 (Trial 2):** - Mass of KHP: 0.3040 g - Final Buret Reading: 31.80 mL 3. **KHP 3 (Trial 3):** - Mass of KHP: 0.3059 g - Final Buret Reading: 15.3 mL **Additional Parameters:** - Buret was initialized at 0.00 mL for all trials. - Total volume dispensed during trials varied. **NaOH Solution:** - Volume of NaOH used: Not explicitly defined in this document. - Molarity of NaOH solution: Not provided here. - Average NaOH Concentration Added: 0.0938M #### Explanation This data sheet contains measurements and calculated concentrations for a series of titration trials involving KHP and NaOH. Each trial records the mass of KHP used, the corresponding volume of NaOH dispensed from a buret, and the average concentration of NaOH across trials. This information is essential for determining the molarity of the NaOH solution used in the titration process. ### Conclusion This experiment demonstrates the practical application of titration in determining the concentration of a solution. The data would typically be used to calculate the exact concentration of NaOH based on standard titration calculations.

Expert Solution
Step 1

Given:

  Trial-1 Trial-2 Trial-
Mass of KHP (g) 0.3130 0.3040  0.3059
Final burette reading (mL) 16.72  31.80  15.30
Initial Burette reading (mL) 1.20 16.72 0.00
Volume of NaOH (mL) 15.52 15.08 15.30

Molarity of NaOH = 0.0988 M

molar mass of KHP = 204.2 g/mol
