Chapter 24, Problem 102A

Interpretation Introduction

Interpretation:

Buffer and its presence in body fluid is to be explained.

Concept introduction:

Buffer resists any change in $\text{pH}$ of the solution by nullifying the effect of any small addition of acid or base in solution. Examples of buffer are weak conjugate-acid base pairs. They have various important applications.

Answer to Problem 102A

Buffer resists any change in $\text{pH}$ of the solution. It is important for body fluids as it absorbs ${\text{H}}^{+}/{\text{OH}}^{\text{-}}$ from food or cellular processes to maintain $\text{pH}$.

Explanation of Solution

Buffer resists any change in $\text{pH}$ of the solution by nullifying the effect of any small addition of acid or base in solution.

Buffer is important for body fluids as it absorbs ${\text{H}}^{+}/{\text{OH}}^{\text{-}}$ from food or cellular processes to maintain $\text{pH}$. Acid-base pairs are used as buffers.

Conclusion

Buffer resists any change in $\text{pH}$ of the solution. It is important for body fluids as it absorbs ${\text{H}}^{+}/{\text{OH}}^{\text{-}}$ from food or cellular processes to maintain $\text{pH}$.
