Chapter 16, Problem 18PE

Interpretation Introduction

Interpretation:

Change due to resistance of carbonic acid-sodium hydrogen carbonate buffer occurs in $\text{pH}$ as excess of ${\text{OH}}^{-}$ gets into bloodstream has to be explained.

Concept Introduction:

Solution that causes resistance in change of $\text{pH}$ due to dilution or addition of acid is termed as buffer solution. Two types of buffer solutions are as follows:

1 Weak acid mixed with salt of its conjugate base

2 Weak acid mixed with salt of its conjugate acid
