Question
Chapter 7, Problem 37P
Interpretation Introduction
Interpretation:
The aqueous solution with highest and lowest pH value should be identified from the given solutions.
Concept Introduction:
The pH of a solution is defined as negative log of hydrogen ion concentration. It is mathematically represented as follows:
Here, 
is concentration of hydrogen ion in the solution.
Also, acids have lower value of pH or higher concentration of hydrogen ion and bases have higher value of pH or lower value of hydrogen ion concentration. Stronger the acid, higher is the concentration of hydrogen ion and strongest the base, higher is the concentration of hydroxide ion or lower is the hydrogen ion concentration.
