Titration lab
The study of acid-base titrations involves consideration of the reactants which occur between acids and bases. For this purpose, it is convenient to distinguish between strong and weak acids and bases. The term "strong" usually refers to a substance which is completely dissociated into its component ions in a solution, while "weak" generally refers to a substance which is only partially dissociated. The principle of this experiment was to find out if the label on the bottle of vinegar was correctly displaying the percent mass of acetic acid as 5 percent through titration. Titration involves the process, operation, or method of determining the concentration of a substance in solution by adding to it a standard reagent of known concentration in carefully measured amounts until a reaction of definite and known proportion is completed, as shown by a color change or by electrical measurement, and then calculating the unknown concentration. In this experiment the technique of titration was used to determine the concentration of solutions of acids and bases. By carrying out this process, concentration of the unknown solution can be calculated. In this lab, vinegar was added to a flask, as well as the color indica
Fill up an Erlenmeyer flask with 10 mL of the acid solution. 11 moles acetic acid 60 grams acetic acid 66. Begin the process of titration by progressively adding NaOH from the BASE buret into the flask. 0-mL samples of the unknown acid solution (recording the precise value of the volume each time), and put two drops of phenolphthalein in each. Add drops of solution from the ACID buret until the solution turns transparent again. 70 M NaOH* 2 - 50 mL burets* 3 - 100 mL beakers* 125 mL Erlenmeyer flask* Double buret clamp* Vinegar solution* Phenolphthalein indicator* Ring stand* Wash bottleProcedure1. Therefore percent error (accepted value- measured value) accepted value was 33 %. Label the burets, along with the two 100 mL beakers as ACID and BASE.
