Part II

  1. What is pH? PH is a form of measurement that is used to determine how extreme the concentration of hydrogen or hydroxide ions is in a sample. PH ranges from 0 to 14, where samples with 0 to 6 concentration on the PH scale are acidic, 7 being neutral and 8 to 14 being alkaline.
  2. What is a base? Any solution has hydroxide ions in it. In this case, it reads between 7 and 14 on the PH Scale.
  3. What is an acid? Any solution that has hydrogen ions. It reads 0 and 6 on the PH Scale.
  4. What does it mean if a solution has more hydrogen ions (H+)? It means that it is more acidic. It may be a strong acid reading between 4 and 6 on the PH Scale.
  5. What does it mean if a solution has more hydroxide ions (OH-)? It means that the solution is alkaline. When tested on the PH Scale, it will range from 11 to 14, if it is a strong base.
  6. What does it mean if a solution is neutral? It means that the pH is neither acidic nor basic.
  7. Explain the pH scale and how it is used to indicate acidic, alkaline, and neutral solutions.

An acidic solution will read between 0 to 2, a neutral solution will read 7 while an alkaline solution will read between 8 and 14 on the PH Scale. If the solution is a weak acid, it will range between 0 and 2, while a strong one will range between 4 and 6. An weak alkaline solution will read between 8 and 10 while a strong one will read between 11 and 14.

  1. What does it mean in terms of strength when the pH of an acid changes from 5 to 4? It means that more hydrogen ions have been added and thus the strength of the acidic solution increases.
