WebA solution of 0.80 M acetic acid acid has a pH of 2.50 (show work for calculations). Determine the [H3O+] concentration. Determine the [OH-] concentration. Deterimine the pH of the acetic acid if it is a strong acid. Based on the given pH and the one calculated if acetic acid is a strong acid, is acetic acid a weak acid or a strong acid? Explain. WebThe pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution.
