Part.A: Titrating a unknow NaOH solution with KHP as the primary standard.
PRE-LAB Acid Base Titration Name: 1. Define analyte and titrant. Be careful answering this question, as many internet sources are wrong on this point. In Part A of this experiment, the analyte is and the titrant is- 2. Explain why the molarity of a sodium hydroxide solution cannot be determined exactly by simply weighing out a sample of solid NaOH, dissolving it in a known amount of water, and calculating its molarity based on the mol mass of NaOH and the overall volume of solution 3. Distinguish between the endpoint and the equivalence point in an acid-base titration. Calculate the molarity of a sodium hydroxide solution if a 0.5356 g sample of KHP was dissolved in 50 mL of water and titrated with 20.78 ml of sodium hydroxide to a phenolphthalein endpoint. Use Equation (2). show all work, and circle your final answer. 4.
