Answer:C
Which of the following correctly represents the solutions in increasing order of their hydronium ion concentration?
A. P > Q > R> S B. P > S > Q > R C. S < Q < R< P D. S < P < Q < R
Explanation: The pH of a substance is related to the concentration of hydrogen or hydronium ions. An acid has a high concentration of hydronium ions and a low pH value whereas a base has a high pH value and a low concentration of hydronium ions.
