Interpretation Introduction

Interpretation:

The buffer solutions should be given from the given representations.

Concept introduction:

Buffer solution:

An equal concentrations of conjugate acid-base pair in a solution is known as buffer solution and it will maintain the pH constantly.

Explanation of Solution

Reason for the correct option:

The given representations are,

Figure 1

From the above given representations, pictures (1) and (4) are represents the buffer solutions because they are only have a conjugate acid-base pair.

Reason for the incorrect options:

Pictures (2) and (3) don’t have a conjugate acid-base pair so they are not a buffer solutions.

Conclusion

The pictures (1) and (4) are represents the buffer solutions.

Interpretation Introduction

Interpretation:

The greatest buffer capacity having buffer solutions should be given from the given representations.

Concept introduction:

Buffer solution:

An equal concentrations of conjugate acid-base pair in a solution is known as buffer solution and it will maintain the pH constantly.

The buffer capacity is directly proportional to the concentrations (number) of conjugate acid-base pair in a solution.

Explanation of Solution

Reason for the correct option:

The given representations are,

General Chemistry: Atoms First-Solution Manual, Chapter 15, Problem 15.34CP , additional homework tip 2

Figure 1

From the above given representations, picture (4) has more number of conjugate acid-base pairs than (1) so it has greatest buffer capacity.

Reason for the incorrect options:

Pictures (2) and (3) don’t have a conjugate acid-base pair so they are not a buffer solutions and Pictures (1) has the lower number of conjugate acid-base pair than (4) so it has a smallest buffer capacity than (4).

Conclusion

The pictures (4) has the highest buffer capacity.
