![]() ![]() All the data obtained are recorded and a graph of volume of sodium hydroxide against pH value of KHP are plotted for experiment 1 while a graph of volume of sodium hydroxide against pH value of vinegar is plotted for experiment 2. In experiment 2, vinegar will be used instead of KHP solution. ![]() The titration will be done three times in order to find the average value of the two titrations. The steps were repeated until an equivalent point is reach. The pH of the solution will be check by using a PH meter which has been calibrated before the experiment started. The titration was carried out by allowing a 1mL of sodium hydroxide into the beaker which consists of KHP solution. In experiment 1, sodium hydroxide will be titrated into a potassium hydrogen phthalate solution, KHP. ![]() The titration process will be conducted by using a burette, which is good for dispense small amount of liquid. 1.0 ABSTRACT This experiment is done to resolve the molarity of a solution and the percent by mass of acetic acid in vinegar by titration process with the standardized sodium hydroxide solution. ![]()
