To prepare a buffer properly, it is essential to understand how a buffer is described. Here are three buffers we used. A solution that is 0.10 M HC2H3O2 and 0.10 M NaC2H3O2. One part 0.10 M NH3 mixed with one part 0.10 M NH4Cl A solution that is 0.10 M NH3 and 0.20 M NH4Cl Three parts 0.10 M NH3 mixed with one part 0.10 M HCl For the first and third buffers, the concentrations of each component are explicit. What are the identities of and concentrations of the buffer components in the second and fourth buffers? (Keep in mind that when mixed, the original solutions dilute each other.)
