Problem: 1iii-"hat is the molar concentration of the hydroiodic acid in an available solution? Experimental design: The hvdroiodic acid in the available solution is titrated with a
standard solution of potassium hydroxide. The colour change of bromothvmol blue indicator to green indicates the equivalence point. 21. The following titration procedure is provided for the described experiment. Three errors
occur in the procedure. Identity each mm and provide the wooded procedural steps. Obtain T0 to 00 mL of potassium hydroxide solution in a clean beaker.
Obtain T0 to 00 mL of hydroiodic acid solution in a clean beaker. Set up the burette to contain the hvdroiodic acid solution. Record the initial burette reading. Pipette a 10.00 mL sample of hvdroiodic acid into a volumetric flask. Add 2-3 drops of bromothvmol blue indicator.
Slowly add the titrant to the sample solution until a subtle colour change has occurred. Swirl vigorously. Record the final burette reading. Dispose contents of the flask safelyr and clean the flask. Repeat steps 4 to T until you obtain three consecutive trials within 0.5 to 1.0 mL of
each other. .mPFfii‘u." F” 599“.”
