Abstract This goal of this experiment was to standardize base solutions for use in later labs. The first of the two solutions was a 0.2 molar Sodium Hydroxide, the second was a 0.1 molar Hydrochloric Acid. The titrations in the experiment showed the exact molarity of the student made solutions, helping them in later labs that require the use of these two solutions. I ntroduction Standardizing solutions helped to create the base solutions for the Chemistry Lab. These solutions will be the base molarities for the upcoming labs. The issue of the lab was standardizing the NaOH solution using potassium hydrogen phthalate, or KHP. The next procedure was to titrate and compare the answers to get the actual molarity of the NaOH solution. The next issue was using the NaOH solution to standardize a Hydrochloric Acid solution with a molarity of 0.1. This procedure was also a titration procedure that required exact precision. Background We know that when adding a base (NaOH) to an acid (KHP) this results in a reaction and interaction between the two. This reaction helps neutralize the acid. Method
