You are given 1 liter of each of the
following solutions: 1M HCl, 1M NaOH, 1M NH3 , 1M
HC2H3O2 , 1MNH4Cl,
1MNaC2H3O2

preparing a buffer solution
b) Describe how you would prepare
400 ml a buffer with a pH= 4.74 and a buffer with pH= 9.25
c) Draw titration curves for :
strong acid-strong base, strong acid-weak base, strong base-weak
acid. Label the graph axes, indicate initial pH and pH at
equivalence.
