Discuss the organization of the pH scale, including the location of acids, bases, and neutral substances
What will be an ideal response?
The pH scale is based on the number of hydrogen ions in solution. The pH scale is constructed from zero to 14. Each sequential change of one pH unit represents a ten-fold change in hydrogen ion concentration. Solutions with a pH lower than seven are considered acidic while solutions with a pH greater than seven are considered basic (alkaline). At a pH of seven, the solution is neutral since hydrogen ion concentration equals hydroxyl ion concentration.
