Acid Base Titration

July 29, 2011 Title: This report highlights an test involved with Acid-Base Titration. Introduction: ratification to the Arrhenius theory an harsh can be defined as a substance that dissolves in water and produces hydrogen ions (H+), appeal a paper produces hydroxide ions (OH-). The Bronsted-Lowry theory states that all vitriolics ar proton donors and all meanspiriteds atomic number 18 proton acceptors. A counteraction 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 occur of H+ will be equal to the amount of OH-. The summation of a specific amount of base required to undermine an acid in a smack involves a titration. An proponent number in a sample will swop color when all the H+ from an acid has been modify. The addition of a base should be stopped when the indicant changes color which indeed determines the endingpoint. 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 criticize color in base.

The purpose of this experiment is to prepare a sample for titration with a base, become old(prenominal) with a buret firearm using proper titration technique in reaching an end point. Hypothesis : If I titrate a base of cognise submersion with an acid of noncitizen concentrati on then I can determine the concentration ca! n be reckon because of the titration calculation. Materials : Vinegar Two small beakers (150mL) 250-mL Erlenmeyer flask 10-mL graduated cylinder 50-mL buret Buret clamp Small funnel M NaOH Hazards : Chemical spill Broken glass surgical unconscious process: Obtain about 20 mL of vinegar in a small beaker. Record the brand of vinegar and the %...If you motive to get a full essay, order it on our website: OrderEssay.net
