The pH of a sample of water that had 10 times the concentration of H⁺ ions as a sample with a pH of 5.8 would be A) 3.8. B) 4.8. C) 6.8. D) 15.8.

Question

Quizplus · Accepted Answer

The pH scale is logarithmic, so a tenfold increase in H⁺ ion concentration decreases the pH by 1 unit. Therefore, a sample with 10 times the concentration of H⁺ ions as a sample with a pH of 5.8 would have a pH of 4.8.
