To determine the weight-to-volume percent of acetic acid present in commercial vinegar and the weight-etc:-volume percent of ammonia present in window cleaners Acid-base iterations can be conducted using the above samples against standardized aqueous Noah and standardized aqueous HCI solutions respectively. 2. Introduction: Acetic acid, commonly known as ethanol acid CHOOSE, is found in commercial vinegar. It is a weak organic acid that gives vinegar its characteristic pungent smell, sour taste and slight acidity.
Being an acid, vinegar is used as a mild disinfectant in cleaning agents as well as a food preservative. Ammonia, NH, is used in household and industrial cleaning agents due to its ability to solubility grease. In this experiment, we shall use acid-base titration to determine the weight-to-volume percentage of acetic acid and ammonia. An acid-base titration is a process of obtaining quantitative information of a sample using an acid. Base reaction why reacting with a certain volume of reactant whose concentration s known.
A suitable indicator for determining the equivalence point is used to indicate the end point of an acid-base titration. To achieve accurate results, multiple iterations will be carried out until duplicate determinations agree to within.
