Acid-Base Titration Background Information A titration is a controlled addition of one substance into another substance. In an acid-base titration‚ the experimenter will add a base of known concentration to an acid of unknown concentration (or vice-versa). The goal of the titration is usually to use the substance of known concentration to determine the concentration of the other substance. In order to run a titration‚ the following materials are needed: • A buret filled with the base (or acid) of

A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated. Theory: Solutions

Abstract The purpose of this experiment is to determine the concentration of acetic acid in vinegar by using 0.1 M HCl and NaOH solution. By performing three titrations to determine the concentration of the base‚ the concentration of the acid was determined to be 0.600 M. It was possible to determine its concentration by standardizing the sodium hydroxide solution used for the first three titrations and by using phenolphthalein to indicate its equivalence point. In conclusion‚ although there were

BASIC means Beginners’ All-purpose Symbolic Instruction Code. There are many versions of VB exist in the market‚ the most popular one and still widely used by many VB programmers is none other than Visual Basic 6. We also have VB.net‚ VB2005‚ VB2008 and the latest VB2010. Both Vb2008

KCL uses node currents and then applies Ohm’s law to derive an equation in terms of node voltages‚ resistors‚ and source voltages. These two laws are only needed when there is: known resistors‚
