steps: Obtain 70 to 80 mL of potassium hydroxide solution in a clean beaker./ 2- Obtain 70 to 80 mL of hydroiodic acid solution in a clean beaker./ 3- Set up the burette to contain the hydroiodic acid solution./ 4- Record the initial burette reading. / 5- Pipette a 10.00 mL sample of hydroiodic acid into a volumetric ask. Add 2-3 drops of bromothymol blue indicator./ 6- Slowly add the titrant to the sample solution until a subtle colour change has occurred. Swirl vigorously. 7- Record the final burette reading./ 8- Dispose contents of the ask safely and clean the ask./ 9 -Repeat steps 4 to 7 until you obtain three consecutive trials within 0.5 to 1.0 mL of each other.
Problem: What is the molar concentration of the hydroiodic acid in an available solution? / Experimental design: The hydroiodic acid in the available solution is titrated with a standard solution of potassium hydroxide. The colour change of bromothymol blue indicator to green indicates the equivalence point./ The following titration procedure is provided for the described experiment. Three errors occur in the procedure. Identify each error and provide the corrected procedural steps:
