Determination of Acetic Acid in Vinegar using a pH Electrode Bryan Nuno Group: (Black) 212 Peter Ruggles Introduction: In the first investigation of the lab, the objective was to take the different household items and determine the pH of each of them. In investigation two, the objective was to use acetic acid in distilled white vinegar and find the percent composition of it. In the first investigation of the laboratory, it was important to find whether the household items were basic or acidic. To continue through the experiment, a temperature probe and pH electrode was used. It would be classified as a base, if the number given by the probe was higher than seven. It is considered an acid, if the number given by the probe was lower than seven. If the number was seven it would be classified as neutral. Water and acetic acid is what makes up Vinegar. It was important to know what vinegar was made up of to fine the percent composition when continuing on with the second investigation of this laboratory. A process called titration must be performed, before calculating the percent composition of acetic acid in vinegar. Titration is a strategy that helps in determining the exact quantity of the reactant in the titration flask and the exact endpoint of a reaction. To deliver the second reactant to the flask a buret is used. To note the endpoint of the reaction, a pH electrode probe is placed in the reactant. In understanding and finding out the results of the laboratory, it is important to know its components, find the percent composition to see how much acetic acid is in vinegar, and to find the pH solution of vinegar. Experimental Investigation One: First, be sure that the temperature and the pH electrode are set up and are connected to LoggerPro software. Rinse the probe with distilled water after you unscrew the top cap and then dry afterwards. To calibrate the
