A general procedure for this titration is described below and will be outlined during our class discussion. , Australia The theory of acids and bases, like many other chemical theories, has undergone. In this experiment an acid-base titration will be used to determine the molar concentration of a sodium hydroxide (NaOH) solution. An acid is sour tasting, and gives a sharp stinging pain in a cut or wound, and bases taste bitter, and feel slippery. An acid-base titration is a process of obtaining quantitative information of a sample using an acid-base reaction by reacting with a certain volume of reactant whose concentration is known. Deciding which indicator to use depends on the types of titration. • The method is easy to use if the quantitative relationship between two reacting solutions is known. Students are asked to predict and test how the the titration end point will shift when titrating vinegar (a weak acid) with NaOH (a strong base). Be especially careful when handling the sodium hydroxide base (NaOH), as it is corrosive. 2mL i've found Vlume of base added is 14.
