Acid-Base Titration Experiment 20C Objective: To titrate a hydrochloric acid solution of unknown concentration with standardized 0.50 M sodium hydroxide and to utilize the titration data to calculate the molarity of the hydrochloric acid, and the molarity. Materiel: Refer to Heath Lab Manual page 236 Procedure: Prepare for lab. Put on apron and goggles. Take 50 mL of the hydrochloric acid solution of unknown concentration and about 100 mL of the standardized NaOH solution. Record the value in Table. …

…Record the volume of NaOH needed to reach the equivalence point in your copy table 1, and repeat the procedure again from getting 10.0 mL sample of HCL and compare the result. Mix any leftover acids and bases together to neutralize, and pour down the sink with plenty of water. Data and Observation: MOLARITY OF NaOH TRIAL 1 TRAIL 2 TRAIL 3 Initial volume of NaOH (mL) Final volume of NaOH (mL) Volume of NaOH used Average volume of NaOH
