Kayla PeterpaulProf. MistryGeneral Chemistry Lab30 October 2017Partner: Rebecca SteinbergerExperiment #20: Titration of Acids and BasesAbstractThe Titration of Acids and Bases lab is based on the principles of the reaction that occurs between an acid and a base, also known as neutralization. During the reaction, hydronium ions and hydroxide ions combine in an aqueous solution to form water. The purpose of this lab is to become familiar with the techniques of titration, which is defined as the technique of accurately measuring the volume of a solution required to react with another reagent. Standardization is another method used, which is the process of determining the concentration of a solution. This can usually be achieved using an indicator solution, which changes colors when equivalent amount of acid and base are present. The color change is called the end point. When the stoichiometrically equivalent quantities are brought together, this is known as the equivalence point. In this lab, we used the reaction between NaOH and KHP to determine the amount of sodium hydroxide in the solution prepared as well as the reaction between unknown acid #4 and NaOH to determine the amount of acid in the unknown. The results showed the amount of sodium hydroxide present and the amount of acid present in the unknown clearly, thus making the experiment a success.IntroductionIn this experiment, the solution of NaOH will be standardized by titrating it against a verypure sample of potassium hydrogen phthalate, which contains one acidic hydrogen. It is called a primary standard and can be obtained in a very pure form which is stable. It is a monoprotic acid
