Quizplus · Accepted Answer

pH is defined as the negative logarithm of the hydrogen ion concentration in a solution, which means it measures the concentration of hydrogen ions in a solution. Therefore, choice A is the correct answer. Choice B is incorrect because the pH scale typically ranges from 0 to 14, not 5 to 8. Choice C is incorrect because the pH scale is a logarithmic scale, not a linear scale. Choice D is incorrect because pH has nothing to do with helium, and choice E is incorrect because it measures the concentration of OH⁻ (hydroxide ions), not the hydrogen ion concentration.
