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...

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.

A solution of NaOH has an unknown concentration. When 1.396 g of potassium hydrogen phthalate (KHP a monoprotic acid frequently used as an analytical standard) is titrated with the sodium hydroxide the end point is 42.54 mL. Use this information to compute the concentration of NaOH in the solution. The molar mass of KHP is 204.22 g mol1. [OH mol L

As part of Lab 11 you will make and standardize a solution of NaOH(aq). Suppose in the lab you measure the solid NaOH and dissolve it into 100.0 mL of water. You then measure 0.1993 g of KHP (204.22 g/mol) and place it in a clean, dry 100-mL beaker, and then dissolve the KHP in about 25 mL of water and add a couple of drops of phenolphthalein indicator. You titrate this with your NaOH(aq) solution and find that the...
