An acidic solution is diluted until [H₃O⁺] is exactly half as much as before. The pH of the solution is now ____ than before. A) 2.00 higher B) 0.69 higher C) 0.30 lower D) 0.30 higher E) 2.00 lower

Question

Quizplus · Accepted Answer

When the concentration of H₃O⁺ is halved, the pH increases by 0.30 because pH = -log[H₃O⁺], and halving the concentration results in a log change of 0.30.
