Pre-laboratory Assignment Name: Read the experiment and answer the following questions as directed by your instructor. 1. In this experiment, you will use potassium hydrogen phthalate (abbreviation KHP, formula HKCH.0) to standardize (to determine the concentration precisely of) the NaOH solution. What is the molar mass of KHP? 2. In Part 1, you will titrate a weighed mass of KHP (dissolved in water) with the unknown NaOH solution. What data must you collect in order to find [NaOH)? List the...
