Chemistry

To prepare a buffer properly, it is essential to understand howa buffer is described. Here are four buffers used:

1. A solution that is 0.1 M HC2H3O2 and 0.10 M NaC2H3O2

2. One part 0.10 M NH3 mixed with one part 0.10 M NH4Cl

3. A solution that is 0.10 M NH3 and 0.20 M NH4Cl

4. Three parts 0.10 M NH3 mixed with one part 0.10 M HCl

For the first and third buffers, the concentrations of eachcomponent are explicit. What are the identities of andconcentrations of the buffer components in the second and thirdbuffers? (Keep in mind when mixed, the original solutions diluteeach other)

Buffer 2:

Buffer 4:
