Interactive Example 4.14 - Neutralization Titration A student carries out an experiment to standardize (determine the exact concentration of) a sodium hydroxide solution To do this, the student weighs out a 1.3009-g sample of potassium hydrogen phthalate (KHC8H404, often abbreviated KHP) KHP (molar mass 204.22 g/mol) has one acidic hydrogen The student dissolves the KHP in distilled water, adds phenolphthalein as an indicator, and titrates the resulting solution with the sodium hydroxide solution to the phenolphthalein endpoint The difference between the final and initial buret readings indicates that 41.20 mL of the sodium hydroxide solution is required to react exactly with the 1.3009 g KHP Calculate the concentration of the sodium hydroxide solution

Question
Interactive Example 4.14 - Neutralization Titration
A student carries out an experiment to standardize (determine the exact concentration of) a sodium hydroxide solution
To do this, the student weighs out a 1.3009-g sample of potassium hydrogen phthalate (KHC8H404, often abbreviated
KHP) KHP (molar mass 204.22 g/mol) has one acidic hydrogen
The student dissolves the KHP in distilled water, adds phenolphthalein as an indicator, and titrates the resulting
solution with the sodium hydroxide solution to the phenolphthalein endpoint
The difference between the final and initial buret readings indicates that 41.20 mL of the sodium hydroxide solution is
required to react exactly with the 1.3009 g KHP
Calculate the concentration of the sodium hydroxide solution
