How is pH defined?
 
  a. Log of the dissociation constant of the weak acid in a solution.
  b. Negative logarithm of the H+ ion concen-tration of a solution.
  c. Point at which an electrolyte solution is exactly 50 dissociated.
  d. Ratio of a solution's weak acid concentra-tion to its conjugate base pair.

Question 2

Which of the following describes an aspect of pH?
 
  a. Any solution with a pH of 7.0 is neutral.
  b. A pH of 7.0 describes an acidotic solution.
  c. A pH change from 7.0 to 8.0 equals a two-fold increase in H+ ion concentration.
  d. The pH is the log of the OH- ion concen-tration.

Answer to Question 1

ANS: B
pH is the negative logarithm of the H+ used as a positive number.

Answer to Question 2
