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.

Answer:

Diffusion rate is 1.96 × $10^{-3}$ $cm^{2}$ /s

Explanation:

Diffusion is the process in which the molecules of a substance propagates from a region of higher concentration to region of lower concentration through a semi-permeable membrane.

diffusion rate = $\frac{area}{time}$
