Question
Chapter 1, Problem 20P
Interpretation Introduction
Interpretation:
A plot for pH as a function of drops of added NaOH solution in given phosphoric acid needs to be sketched.
Concept introduction:
pH is a degree of the hydrogen ion concentration of a solution. Solutions having a high concentration of hydrogen ions contain a low pH and solutions having a low concentration of H+ ions contain a high pH.

More ratios. Through the use of nuclear magnetic resonance
spectroscopy, it is possible to determine the ratio between the
protonated and deprotonated forms of buffers. (a) Suppose the ratio
of [ A- ]A I to [HA] is determined to be 0.1 for a buffer with
pKar6.0.pKa = 6.0. What is the pH? (b) For a different buffer,
