Lab 14: Titration Lab by Katie, Maya, Alison and Meghana

In this lab we used a very stressful, difficult, and painstaking process called titration. We combined acid (vinegar) and a base (NaOH). An indicator, phenolphthalein, was used to tell when the solution went from its acidic form to basic form. At this point we would know the volume of the base and could use MV=MV to solve for the molarity of the acid. Then we used the pH of the base to find molarity of the base, and used this to find percent ionization. The ionization of vinegar was .456%. It is low because vinegar is a weak acid and so very few of its molecules ionize and become ions. 

We used a barrette to carefully combine the base and acid. The acid was distilled in water and we kept adding more base until the indicator showed that the solution had made the transformation.
