Exercise care to avoid overshooting the endpoint (intense pinkish-red color). If you do accidentally overshoot the endpoint, weigh a fresh sample of KHP and repeat the titration. 7. Titrate two (or three, if time permits) separate weighed samples of KHP. 8. Calculate the moles of KHP, NaOH, and the molarity of the NaOH.
2. Look up the molecular weight for potassium hydro KHP in 0.409 g of KHP. potassium hydrogen phthalate (KHP) and determine the number IP) and determine the number moles of 3. The 0.409 g of KHP is dissolved in 100 mL of NaOH (aq) to the faint pink endpoint. A snapshot of the burette before (left) and after the NaOH (aq) titrant.

Chemistry questions and answers. In the quantitative analysis lab, a student analysis a sample of impure potassium hydrogen phthalate (KHP) and reports a 22.58% KHP content in the sample as the mean of 3 replicate measurements and a standard deviation of 0.55 of % KHP. Tie manufacturer indicates the sample to be 24.02% KHP.
A student titrates an unknown amount of potassium hydrogen phthalate (KHC8H4O4, often abbreviated KHP) with 20.40 mL of a 0.1600-M NaOH solution. KHP (molar mass = 204.22 g/mol) has one acidic hydrogen. What mass of KHP was titrated (reacted completely) by the sodium hydroxide solution?Mass = g.
Question: Standardization of NaOH using KHP Objective: In this lab you will accurately determine the concentration of a solution of sodium hydroxide (NaOH) using a 0.500 M potassium hydrogen phthalate (KHP) standard solution. Acid-base indicator phenolphthalein will be added in its (colorless) acidic form to a known volume of KHP.
Potassium hydrogen phthalate (abbreviated as KHP ) has the molecular formula KHC8H4O4 and a molar mass of 204.22gmol. KHP has one acidic hydrogen.A 0.4795g sample of KHP is dissolved in 35mL of water and titrated to the equivalence point with 23.63mL of a sodium hydroxide ( NaOH ) solution.What is the concentration of ...
