Name: Liliana Barbeito Logan/zaia Postlab: Buffers and Their Properties Lab Partner: Procedure: Part 1: Preparation of a buffer: On the lab bench you have 0.10M stock solutions that can be used to make an acetic acid, HCH3O2, sodium acetate, NaC2H3O2, buffer. Date: 1. Using a graduated cylinder, measure out 15mL of acetic acid and pour it into a 100mL beaker. Rinse the graduated cylinder with distilled water, then measure out 15mL of the sodium acetate and pour it into the 100mL beaker. 7/6/2023 2. Measure the pH of your buffer mixture and record it in your data table. Calculate pKa for the buffer. pH of buffer: 4.56 pH of diluted buffer: 4.46 3. Pour half of the buffer into another beaker and add 30mL of water to your buffer mixture and stir with a glass stirring rod. This is the diluted buffer. Measure the pH of the diluted buffer mixture, record the pH in your data table, and calculate pKa. pKa pKa equation? Question: 1) Comment on your observations between the pH's of the buffer and the buffer diluted
