Which of the following statements about pH is true?

WebbWays of Measuring pH. The methods for measuring pH fall roughly into the following four categories: Indicator methods. Metal-electrode methods (including the hydrogen … WebbThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.

WebbA pH value is actually a measure of hydrogen ion concentration. Because hydrogen ion concentration varies over a wide range, a logarithmic scale (pH) is used: for a pH decrease of 1, the acidity increases by a factor of 10. It is a ‘reverse’ scale in that a very acid soil has a low pH and a high hydrogen ion concentration. Webb9 sep. 2024 · The pH scale is a familiar concept for students who study science. The pH value of a solution reflects the relative concentration of hydrogen ions (H+) or protons to the concentration of hydroxide ions (OH-) in a solution. Solutions with a pH value less than 7 are acidic and those with a value greater than 7 are basic, or alkaline.
