Title: Titrations and titration curves Purpose: The purpose of this to perform titration analyses, including neutralization titrations, which occur between an acid and a base. Procedure: After gathering the necessary supplies, it was decided that we would perform reactions between the following solutions: strong acid/strong base, weak acid/strong base and strong acid/weak base. Standardization titration of NaOH: Used a strong acid/weak base. We determine the molarity of the N...
