In 250 mL beakers, obtain just enough of the 0.1 M weak acid and conjugate base solutions to make all of the following solutions. In clean labeled 100 mL beakers, prepare 30.0 mL of each buffer solution with the following volume ratios of acid to base: 1:1, 4:1, 9:1, 1:4, 1:9. Write out a detailed procedure for making each of these solutions and how much of the stock acid and conjugate base stock solutions you will need to use.
