Answer to Question 1

ANS: C
Sorenson introduced the term pH as a shorthand way to express the hydrogen ion activity of so-lutions. It is defined as the negative logarithm (base 10) of the hydrogen ion concentration, or pH = log10H+.

Answer to Question 2

ANS: B
In general chemistry textbooks, a pH of 7 represents universal neutrality, where the concentration of hydrogen ions (1  107 mol/L) and hydroxyl ions (1  107 mol/L) is equal. This is the pH of pure water.
