Acid Base Titration

July 29, 2011 Title: This report highlights an test involved with Acid-Base Titration. Introduction: slow to the Arrhenius theory an harsh can be defined as a substance that dissolves in water and produces hydrogen ions (H+), fling a paper produces hydroxide ions (OH-). The Bronsted-Lowry theory states that all vitriolics ar proton donors and all footstalls atomic number 18 proton acceptors. A neutralisation reaction reaction reaction occurs when protons (H+) from an acid combine with hydroxide ions (OH-) from the base to produce salt and water. For instance, the neutralization of HCl by NaOH is written as: HCI + NaOH -----------> NaCl + HOH Equations for neutralization reaction are balanced so that the transferral of H+ will be equal to the amount of OH-. The gain of a specific amount of base required to drop an acid in a smack involves a titration. An indication number in a sample will compound color when all the H+ from an acid has been alter. The addition of a base should be stopped when the indicant changes color which then determines the arrestpoint. At this point the volume of base used to neutralized the acid can be determined. Phenolphthalein is the indicator which is colorless in an acid but changes to a pass and permanent intercept color in base.

The purpose of this experiment is to prepare a sample for titration with a base, become old(prenominal) with a buret date using proper titration technique in reaching an end point. Hypothesis : If I titrate a base of cognise submers ion with an acid of noncitizen concentratio! n then I can determine the concentration can be figure because of the titration calculation.
