You have been given a vinegar solution that is made of water and an unknown concentration (M) of acetic acid. Acetic acid is a monoprotic acid which reacts with NaOH in a 1:1 mole ratio. You have access to a premade NaOH solution of unknown concentration (M), potassium hydrogen phthalate (KHP) and an phenolphthalein indicator as well. Using whatever necessary glassware that would be available to you in the general chemistry lab, design an experiment to determine the Molarity concentration (M), and appropriate statistics, of the acetic acid in the vinegar solution. Write the procedure, including specific glassware, measurements, and calculations in a bulleted or numbered list.

5. You will also make other concentrations of solutions. If the concentration is to be less than a mole, reduce the mass of the substance accordingly. If the concentration is to be greater than 1M, increase BIOL 1406 the mass added or reduce the volume of water accordingly. Use this formula: Molarity = moles/liter. Example: Make a .5M solution of HCI Name: H = 1.008 Daltons CI = 35.45 Daltons Total = 36.46 Daltons = 36.46 grams .5M = X moles/1 liter .5M * 1 liter = X moles Date Number of moles = .5 .5 * 36.46 = 18.23 grams Add 500 mLs water to 1L volumetric flask, add the 18.23 grams HCI to the water, swirl to dissolve, then add water until it reaches the 1L or 1,000 mL mark.

sentences. 3. Virtual Lab Questions a. A student prepares a solution of hydrochloric acid that is approximately 0.1 M and wishes to determine its exact concentration. A 25.00 mL portion of the HCI solution is transferred to a flask, and after a few drops of indicator are added, the HCI solution is titrated with 0.07575 M NaOH solution. The titration requires exactly 38.92 mL of the standard NaOH solution to reach the end point. What is the molarity of the HCI solution? b. It takes 46.22 mL of a 1.021 M NaOH solution to neutralize a solution of 4.4567 g of an unknown monoprotic acid in 80.00 mL of water. Calculate the molecular weight of the acid. 4(D) 5
