pH GRADE A Q&A
A solution containing HCl would likely have - (correct answer)a low pH and a high pOH.
The pH of a solution decreases by 2.0. How does the hydronium ion concentration of
the solution change? - (correct answer)increases to 100 times the original concentration
Which describes an alkaline solution? - (correct answer)acidic (NOT CORRECT)
Which of these correctly defines the pH of a solution? - (correct answer)the negative log
of the hydronium ion concentration
What is the pH of a solution with [H+] = 1.25 mc015-1.jpg 10-10 M?
Use mc015-2.jpg. - (correct answer)9.90
Which statement best describes the pH of pure water? - (correct answer)It is neutral
because the concentration of hydronium ions equals that of hydroxide ions.
How can the pH of a solution be calculated if the pOH is known? - (correct answer)by
subtracting the pOH from 14
What is the equilibrium constant of pure water at 25°C? - (correct answer)10-14
A substance with a high [H+ ] would likely have which additional characteristics? -
(correct answer)a low [OH- ] and a low pOH (NOT CORRECT)
Which would most likely be the pH of a highly-corrosive acid? - (correct answer)1
