ANATOMY

Detailed explanation-1: -If a solution has the lowest possible concentration of hydrogens, it will have pH of 14, since that is the lowest value that is possible in aqueous solution.

Detailed explanation-2: -In both cases, this pH test measures the amount of hydrogen ions (H+) that exists in a given solution. High concentrations of hydrogen ions yield a low pH, whereas low levels of hydrogen ions result in a high pH.

Detailed explanation-3: -The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale (Figure 1). Therefore, the more hydrogen ions present, the lower the pH; conversely, the fewer hydrogen ions, the higher the pH.

Detailed explanation-4: -The pH value of a solution directly measures the concentration of hydrogen ions (H+) in the solution. Acids have a large H+ concentration, which translates to a small pH value. Bases have very little H+. Basic solutions have large pH values-greater than pH 7.
