Question

pH
A. is a measure of the hydrogen ion concentration.
B. utilizes a scale from 5 to 8.
C. is a linear (not logarithmic) scale.
D. is an abbreviation for, "power of helium".
E. is a measure of the hydrogen ion concentration, utilizes a scale from 5 to 8 AND is a linear (not logarithmic) scale

Answer 1

The correct answer is A. is a measure of the hydrogen ion concentration.

Explanation:

The pH determines how acid or alkaline a substance is, usually by classifying substances and mainly solutions on a scale from 0 to 14, in which 7 represents a neutral substance. This property is determined based on the hydrogen ion concentration, in this way a substance with a high hydrogen ion concentration is more acid that one with a low hydrogen ion concentration. Additionally, in this scale solutions are classified as acidic if they have a pH lower than 7 or as basic if the pH is higher than 7. According to this, it can be concluded pH is a measure of the hydrogen ion concentration.
