Acid Base Titration

July 29, 2011

Title:
This report highlights an test involved with Acid-Base Titration.
Introduction: check to the Arrhenius theory an harsh can be defined as a substance that dissolves in water and produces hydrogen ions (H+), spell a paper produces hydroxide ions (OH-). The Bronsted-Lowry theory states that all vitriolics ar proton donors and all bases atomic number 18 proton acceptors.
A neutralization 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 fare of H+ will be equal to the amount of OH-.
The addition of a specific amount of base required to neutralize an acid in a smack involves a titration. An index number in a sample will change color when all the H+ from an acid has been neutralized. The addition of a base should be stopped when the indicant changes color which therefore determines the endpoint. 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 pink color in base.




The purpose of this experiment is to prepare a sample for titration with a base, become old(prenominal) with a buret while using proper titration technique in reaching an end point.
Hypothesis :
If I titrate a base of known submersion with an acid of noncitizen concentration then I can determine the concentration can be calculated because of the titration calculation.
