Complete the flow chart with the steps necessary for preparing the buffer solutions. in beakers, obtain of the 0.1 m weak acid and of the conjugate base stock solutions. this will be your supply to make the buffer solutions. prepare of the assigned 1: 1 buffer solution in a clean, labeled 100 ml . you will need to use of the 0.1 m weak acid and of the 0.1 m conjugate base. measure out the stock solutions using a clean , being sure to rinse it into the waste beaker between each solution to prevent contamination. in your pre‑lab, write out how much weak acid and conjugate base will be used to make each of the remaining buffer solutions: 1: 4, 1: 9, 4: 1, 9: 1.
