Date Performed: 10/30/09 Name: Marco Gutierrez Date submitted: 11/06/09 Partners name: Jess Baul Furong Sun Acid Base Titration Objective: To standardize a sodium hydroxide solution by reacting it with a hydrochloric acid solution. Also, to determine the molar mass of an monoprotic acid as well as the percentage of acetylsalicylic acid in an aspirin tablet. Experimental Data: Part A: Molarity of HCL= .200 Sample 1: volume of HCL= 25.0mL Volume of NaOH= 20.00 Sample 2: volume of HCL= 25.0 mL Volume of NaOH= 17.67mL Part B: Sample A Beaker mass= 32.07g Beaker + sample mass= 33.08 g Mass of sample=1.01g Volume of NaOH= 17.59mL Sample B Beaker mass= 32.55g Beaker + sample mass= 33 .55g Sample mass= 1.00g

Volume of NaOH= 19.96g Part C: Aspirin mass= .36g NaOH volume = 7.10mL Sample calculations: Part A: 20.0 mL of NaOH (.200 mol of HCL/L) x (.025L HCL) = .0050 mol HCL (1mol NaOH/1mol HCL) x (.0050 mol HCL) = .0050 mol NaOH .0050 mol NaOH/.020 L NaOH= .250 M NaOH Part B: .250 mol NaOH/ L x .01759 L NaOH= .004 mol NaOH
