Title: Determining the Molarity of a Strong Acid Experiment #3 William Matthew Speight Locker Number: J20-4 Chem 1A, Section 450, Rebecca Petit Purpose: To determine the molarity, or concentration, of the HCl solution with high precision by titration with a strong acid. Methods: First, dilute 5 mL of 5 M HCl with distilled water and fill a buret with the distilled HCl solution. A buret is used to ensure accuracy in the recording of the amount of the HCl solution used. Measure approximately .20g of TRIS and record the exact weight to four decimal places to ensure consistency in the experiment’s outcome. Add water to the TRIS and place the mixture into an Erlenmeyer flask, along with 5 drops of bromocresol green, to indicate when the TRIS mixture is fully titrated. Next, add the HCl solution to the TRIS mixture, constantly stirring, until the mixture turns green. Record the amount of HCl solution consumed. Then, calculate the exact molarity of the HCl solution. Repeat the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
