WebThe pH and pOH is what determines the strength of an acid. As I said before, the pH scale ranges from 1-14. The closer to 0 the solution is, the more acidic said solution is. The closer the pH of the solution is 14, the more basic said solution is. However, when the solution has a pH of 7, then the solution is neutral Web10 mei 2024 · The pH of a solution ranges from 0 to 14. An acid has a pH less than 7. Pure water is neutral and has a pH of 7. The pH of a solution is given by pH = - log x where x represents the concentration of the hydrogen ions in the solution in moles per liter.
