Determining the concentration of HCl by titration with NaOH Preparing your NaOH solution: 1. Weight out approximately ~0.4 grams of NaOH. Do not waste time getting exactly 0.4, because it doesn’t matter. You DO need to write down the exact amount that you used. Amount of NaOH used: ___________________________. 2. Add your NaOH to a 100 mL volumetric flask. 3. Fill the volumetric flask with water up to the line. Cap and shake the solution until all NaOH is dissolved. 4. Calculate the molarity of the NaOH solution: Concentration of NaOH: _______________________________. Preparing your burets: 5. Label one buret as "HCl" or “Acid” and the other as "NaOH" or “Base”. These may be already labeled for you. 6. Rinse the HCl buret with your unknown HCl solution. Rinse the NaOH buret with your NaOH solution. 7. Using a funnel, fill both burets with the appropriate solution. DO NOT SHARE OR CROSS-CONTAMINATE FUNNELS! You may want to label the funnels as “Acid” or “Base” as well.

    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.
